Security Vulnerabilities - CVEs Published In August 2022
When a POST request comes through AJP and the request exceeds the max-post-size limit (maxEntitySize), Undertow's AjpServerRequestConduit implementation closes a connection without sending any response to the client/proxy. This behavior results in that a front-end proxy marking the backend worker (application server) as an error state and not forward requests to the worker for a while. In mod_cluster, this continues until the next STATUS request (10 seconds intervals) from the application server updates the server state. So, in the worst case, it can result in "All workers are in error state" and mod_cluster responds "503 Service Unavailable" for a while (up to 10 seconds). In mod_proxy_balancer, it does not forward requests to the worker until the "retry" timeout passes. However, luckily, mod_proxy_balancer has "forcerecovery" setting (On by default; this parameter can force the immediate recovery of all workers without considering the retry parameter of the workers if all workers of a balancer are in error state.). So, unlike mod_cluster, mod_proxy_balancer does not result in responding "503 Service Unavailable". An attacker could use this behavior to send a malicious request and trigger server errors, resulting in DoS (denial of service). This flaw was fixed in Undertow 2.2.19.Final, Undertow 2.3.0.Alpha2.

An improper access control check in GitLab CE/EE affecting all versions starting from 13.7 before 15.0.5, all versions starting from 15.1 before 15.1.4, all versions starting from 15.2 before 15.2.1 allows a malicious authenticated user to view a public project's Deploy Key's public fingerprint and name when that key has write permission. Note that GitLab never asks for nor stores the private key.

Insufficient validation in GitLab CE/EE affecting all versions from 12.10 prior to 15.0.5, 15.1 prior to 15.1.4, and 15.2 prior to 15.2.1 allows an authenticated and authorised user to import a project that includes branch names which are 40 hexadecimal characters, which could be abused in supply chain attacks where a victim pinned to a specific Git commit of the project.
