## Goroutine Leak in Abacus SSE Implementation ### Summary A critical goroutine leak vulnerability has been identified in the Abacus server's Server-Sent Events (SSE) implementation. The issue occurs when clients disconnect from the `/stream` endpoint, as the server fails to properly clean up resources and terminate associated goroutines. This leads to resource exhaustion where the server continues running but eventually stops accepting new SSE connections while maintaining high memory usage. The vulnerability specifically involves improper channel cleanup in the event handling mechanism, causing goroutines to remain blocked indefinitely. ### [POC](https://github.com/JasonLovesDoggo/abacus/blob/main/docs/bugs/GHSA-vh64-54px-qgf8/test.py) ### Impact This vulnerability affects all versions of Abacus prior to v1.4.0. The issue causes: - Permanent unresponsiveness of the `/stream` endpoint after prolonged use - Memory growth that stabilizes at a high level but prevents proper functio...
### Impact User enumeration in database authentication in Flask-AppBuilder <= 4.5.3 and werkzeug >= 3.0.0. Allows for a non authenticated user to enumerate existing usernames by timing the response time from the server when brute forcing requests to login. ### Patches Upgrade to flask-appbuilder>=4.5.3 ### Workarounds Downgrade werkzeug to <3.0.0 ### References _Are there any links users can visit to find out more?_
Improper privilege management in a REST interface allowed registered users to access unauthorized resources if the resource ID was known. This issue affects Apache StreamPipes: through 0.95.1. Users are recommended to upgrade to version 0.97.0 which fixes the issue.
Stage.js through 0.8.10 allows DOM Clobbering (with resultant XSS for untrusted input that contains HTML but does not directly contain JavaScript), because document.currentScript lookup can be shadowed by attacker-injected HTML elements.
Prism (aka PrismJS) through 1.29.0 allows DOM Clobbering (with resultant XSS for untrusted input that contains HTML but does not directly contain JavaScript), because document.currentScript lookup can be shadowed by attacker-injected HTML elements.
In oxidized-web (aka Oxidized Web) before 0.15.0, the RANCID migration page allows an unauthenticated user to gain control over the Linux user account that is running oxidized-web.
### Summary Improper validation of select fields allows attackers to craft an input that crashes the system, resulting in a 500 status and making the entire site and administration panel unavailable. This clearly impacts the Availability aspect of the CIA triad (confidentiality, integrity, and availability), although the attack still has certain limitations. ### Details The attack involves injecting any invalid user role value (e.g. ">") into the Role=User parameter in the /panel/users/{name}/profile page, which is the user profile update page. Doing this will change the users data in a way that prevents users and then the entire site from loading. Even though the actual data change is minimal, the error is unrecoverable until a valid role parameter is restored by direct modification of the user account file. Proper validation of select fields will prevent extraneous valid from being accepted and making the entire site and administration panel unavailable. ### Patches - [**Formwork...
### Summary The site title field at /panel/options/site/allows embedding JS tags, which can be used to attack all members of the system. This is a widespread attack and can cause significant damage if there is a considerable number of users. ### Impact The attack is widespread, leveraging what XSS can do. This will undoubtedly impact system availability. ### Patches - [**Formwork 2.x** (aa3e9c6)](https://github.com/getformwork/formwork/commit/aa3e9c684035d9e8495169fde7c57d97faa3f9a2) escapes site title from panel header navigation. ### Details By embedding "<!--", the source code can be rendered non-functional, significantly impacting system availability. However, the attacker would need admin privileges, making the attack more difficult to execute. ### PoC  1. The page where the vulnerability was found, and the attack surface is the Title field.  { String resolved = this.engine.getLoader().resolveRelativ...
Two denial of service vulnerabilities were found in ntpd-rs related to the handling of NTS cookies in our client functionality. Whenever an NTS source is configured and the server behind that source is sending zero-sized cookies or cookies larger than what would fit in our buffer size, ntpd-rs would crash. Only configured NTS sources can abuse these vulnerabilities. NTP sources or third parties that are not configured cannot make use of these vulnerabilities. For zero-sized cookies: a division by zero would force an exit when the number of new cookies that would need to be requested is calculated. In ntpd-rs 1.5.0 a check was added to prevent the division by zero. For large cookies: while trying to send a NTP request with the cookie included, the buffer is too small to handle the cookie and an exit of ntpd-rs is forced once a write to the buffer is attempted. The memory outside the buffer would not be written to in this case. In ntpd-rs 1.5.0 a check was added that prevents accepting...
