CVSS v3.1 |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, a broken access control vulnerability exists in Zammad's GraphQL API. An authenticated user can access taskbar item data belonging to another user by crafting a request with the target user's taskbar identifier. The taskbar feature stores transient state for active user sessions, including auto-saved ticket drafts. Under certain conditions, the authorization check for taskbar item access is not enforced, allowing a user to read another user's taskbar item data. This vulnerability is fixed in 7.0.2. |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, summary An unauthenticated request to POST /api/v1/import/otrs/import_check blocks a Zammad request worker for roughly two minutes. The import_check and import_status actions are missing the setup_done_response guard that other actions in the same controller carry, so they execute on fully set-up production instances. The action enters a retry loop against a blank OTRS endpoint, sleeping for 30 s + 45 s between attempts. Impact An unauthenticated remote attacker denies service to a production Zammad instance. Each request costs almost nothing and forces ~115 seconds of server-side blocking. A few requests per second saturate the Puma worker pool. The condition persists as long as the traffic continues. No account, valid import configuration, or target knowledge beyond the hostname is needed. CSRF token is trivially obtained from any prior GET response. This issue is fixed in version 7.0.2. |
| Adobe Connect is affected by an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could lead to arbitrary file system read. An attacker could exploit this vulnerability to access sensitive files and directories outside the intended access scope. Exploitation of this issue does not require user interaction. Scope is changed. |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, vulnerability in Zammad's HTML sanitization allows injection of specific HTML elements into ticket bodies. When another user views the crafted ticket, the injected element can trigger a logout request, terminating the viewer's session. This vulnerability is fixed in 7.0.2. |
| Adobe Connect is affected by a stored Cross-Site Scripting (XSS) vulnerability that could be abused by an attacker to inject malicious scripts into vulnerable form fields. Malicious JavaScript may be executed in a victim's browser when they browse to the page containing the vulnerable field. Scope is changed. |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, an authorization bypass vulnerability was found that allows an authenticated agent to read knowledge base answer content they should not be able to access. The vulnerable GraphQL mutation is meant to transform a knowledge base answer suggestion so it can be inserted into the ticket editor, but it only checks if the user has the ticket.agent permission. Checking the authorization to the knowledge base answer itself is missing. This vulnerability is fixed in 7.0.2. |
| Metaphor Creations Ditty (ditty-news-ticker) before 3.1.70 contains a stored cross-site scripting vulnerability that allows authenticated users with Author-level privileges or higher to inject arbitrary HTML elements by supplying malicious wrapper attribute values in layout tags. The ditty_layout_render_tag_wrapper() function inserts caller-supplied wrapper attribute values directly as HTML element names without allowlist validation, bypassing wp_kses_post() sanitization because KSES runs at save time before layout tag attributes are resolved at render time, causing the payload to execute in the browser of any visitor viewing posts or pages embedding the affected Ditty item. |
| NVIDIA NeMo Speech for all platforms contains a vulnerability where malicious data created by an attacker could cause remote code execution. A successful exploit of this vulnerability might lead to code execution, information disclosure, and data tampering. |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2 and 7.1.0, this issue concerns a lack of discursive validation within the authorization cascade. It has been determined that the system-level enforcement of access restrictions during the initialization of new identity objects exhibits a discrepancy: Under specific conditions, the granular restrictions of the access key being used are overridden by the latent authorization authority of the parent account. Consequently, this means that the intended separation of functional areas is nullified, resulting in an uncontrolled expansion of administrative discretion. Due to this potential integrity breach of the entire trust environment, an immediate evaluation of the authorization hierarchies is imperative. Impact An attacker can create new administrator accounts despite token restrictions. This grants full access to all system data (tickets, customers, configuration) and allows the attacker to take complete control of the Zammad instance. Abuse Scenario The vulnerability stems from a lack of synergy between the token-based authorization logic and the target system's functional authorization hierarchy, which allows for iterative escalation of the privileged access context. This issue is fixed in versions 7.0.2 and 7.1.0. |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.1, a low-privilege authenticated user may inject arbitrary HTML markup, including JavaScript event handlers, into a ticket title via the standard ticket creation workflow. The title is persisted without sanitization. This issue is fixed in version 7.0.1. |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2 and 7.1.0, zammad's HTML sanitizer (HtmlSanitizer::Strict) blocks external URLs in to prevent remote content loading, but the srcset attribute, also allowlisted for , is not subject to the same check. This oversight allows an attacker to embed arbitrary external URLs in the srcset attribute just by sending an e-mail, effectively bypassing the external content protection. When an agent views the ticket containing the malicious srcset, the browser will silently load the attacker-controlled URL, resulting in the leakage of the agent's IP address, User-Agent, Referer, and the exact time the ticket was viewed. HtmlSanitizer::Strict got extended to block external URLs in the srcset attribute of tags. This was done to prevent tracking pixels and external content loading, which could compromise user privacy. This issue is fixed in versions 7.0.2 and 7.1.0. |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, summary In Zammad's inbound PGP email processing, the return value of the gpg verification call was silently discarded. Regardless of whether gpg reported a valid, invalid, or missing signature, the handler unconditionally wrote sign: { success: true, comment: "Good signature" } to the article's security preferences. Impact Any sender could tamper with the body of a multipart/signed PGP email, or craft a message with an entirely fabricated or mismatched signature, and Zammad would display it to the recipient as cryptographically verified with a "Good signature" label. Users and agents relying on Zammad's signature indicator to confirm message authenticity and integrity would be misled into trusting modified or forged content. The vulnerability affects all inbound PGP-signed emails processed while the PGP integration is enabled. This issue is fixed in version 7.0.2. |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, during federated authentication (OAuth/OIDC/SAML), a profile image URL from the external identity provider is fetched without verifying the target address. An actor who controls their profile at a connected provider may cause the server to connect to internal network locations. Response timing and error patterns differ between reachable and unreachable targets, allowing internal service probing. Worker processes may be blocked for several seconds per request. Requires a configured external authentication provider where the actor can modify their profile image URL. This issue is fixed in version 7.0.2. |
| RouterOS SSH enters the connection protocol after a client-requested rekey even though user authentication was never attempted, allowing an unauthenticated client to open a session channel and send an exec request. On affected builds the server dispatches the command, enabling unauthenticated creation, overwrite, and reconstruction of files in the RouterOS managed file namespace, including support files containing configuration and diagnostic data.This issue was fixed in versions: 6.49.21 (Long-term), 7.23.4 (Long-term) and 7.24.2 (Stable) |
| Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.2, this vulnerability breaks normal ticket isolation boundaries between agents. Any authenticated agent, even one with no active tickets assigned to them, can view the titles, status, labels, and URL links of GitHub/GitLab issues attached to any ticket in the system. This allows an internal user to systematically view GitHub/GitLab issue data linked by other agents or administrators across the organization by simply querying random or sequential ticket IDs. This vulnerability is fixed in 7.0.2. |
| Bludit CMS through 3.22.0 contains an authorization bypass vulnerability that allows authenticated users with the Author role to enumerate and delete media files belonging to pages owned by other users, including administrators, by supplying arbitrary uuid parameters to unprotected AJAX endpoints. Attackers can retrieve page UUIDs for all users via the content-get-list endpoint and then submit crafted POST requests to the list-images and delete-image endpoints in bl-kernel/ajax/ to access and destroy media files outside their own pages, bypassing the IMAGE_RESTRICT isolation control. |
| Improper control of generation of code ('code injection') in Microsoft Office SharePoint allows an authorized attacker to execute code over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
net: bcmasp: clear txcb->last before writing each descriptor
bcmasp_xmit() only wrote txcb->last = true for the final fragment
of an SKB; non-final fragments left the field untouched. If a
descriptor slot was reused while it still held a stale true from
a previous SKB (possible when tx_spb_ring_full() underreported
fullness), bcmasp_tx_reclaim() would see last == true mid-SKB and
call dev_consume_skb_any() prematurely, freeing the sk_buff while
its remaining fragments were still in flight.
Unconditionally clear txcb->last before the conditional set so every
descriptor slot starts from a known false state regardless of what a
prior transmission left behind. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_conntrack_sip: fix OOB read in sip_skip_whitespace()
sip_skip_whitespace() returns dptr unchanged when its own loop
exhausts the buffer (dptr == limit), instead of NULL like its sibling
sip_follow_continuation() returns on its own "no more data" path.
ct_sip_get_header() only checks for NULL after calling it:
dptr = sip_skip_whitespace(dptr, limit);
if (dptr == NULL)
break;
if (*dptr != ':' || ++dptr >= limit)
break;
so a recognized header name followed only by spaces/tabs running to
the exact end of the SIP payload, with no colon, makes the very next
statement read one byte past the buffer.
Make both "no more data" outcomes return NULL, matching the
convention sip_follow_continuation() already uses and that both
existing callers already check for. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix the possible bioc_list memory leak during error
There are two possible ways to leak bioc memory on
btrfs_ordered_extent::bioc_list:
- An error occurred for btrfs_insert_one_raid_extent()
Then the function btrfs_insert_raid_extent() immediately return
without freeing any bioc in the bioc_list.
- An ordered extent hit an IO error
In that case the ordered extent will have BTRFS_ORDERED_IOERR set, and
skip the call on btrfs_insert_raid_extent() completely.
Fix the problem by:
- Introduce a new helper, btrfs_cleanup_ordered_bioc_list()
Which will remove all bioc from the bioc_list, and release the bioc.
- Call the above helper for btrfs_insert_raid_extent()
So that the cleanup helper is always called no matter what.
- Call the above helper for btrfs_finish_one_ordered()
This is called just before the final release on the ordered extent.
This was reported by Sashiko when reviewing another patch. |
