A vulnerability in multiple Atlassian products allows a remote, unauthenticated attacker to bypass Servlet Filters used by first and third party apps. The impact depends on which filters are used by each app, and how the filters are used. This vulnerability can result in authentication bypass and cross-site scripting. Atlassian has released updates that fix the root cause of this vulnerability, but has not exhaustively enumerated all potential consequences of this vulnerability.

Detection & IOCsextracted from sources · hover to see the quote

→CVE-2022-26136 allows remote, unauthenticated attackers to bypass Servlet Filters in multiple Atlassian products, potentially leading to authentication bypass and cross-site scripting. Detection should focus on unexpected or malformed HTTP requests that bypass filter chains in Atlassian application logs. ↗

·Atlassian has not exhaustively enumerated all potential consequences of this vulnerability; the full impact surface depends on which Servlet Filters are deployed by first and third-party apps and how those filters are configured. ↗
·A wide range of Atlassian product versions are affected across Bamboo, Bitbucket, Confluence, Crowd, Fisheye/Crucible, Jira, and Jira Service Management. Ensure all instances are patched to the fixed versions listed in the advisory. ↗
