AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
Unauthenticated attackers can read arbitrary files in WEB-INF and META-INF directories in Jira Server/Data Center via a path access check flaw.
Vulnerability
The CachingResourceDownloadRewriteRule class in Jira Server and Jira Data Center contains an incorrect path access check that allows unauthenticated remote attackers to read arbitrary files within the WEB-INF and META-INF directories. Affected versions are before 8.5.11, from 8.6.0 before 8.13.3, and from 8.14.0 before 8.15.0 [1].
Exploitation
An attacker with network access to the Jira instance can exploit this vulnerability without any authentication. By sending a specially crafted request that bypasses the path validation, the attacker can read files such as web.xml or other configuration files located in the WEB-INF and META-INF directories [1].
Impact
Successful exploitation allows the attacker to read sensitive files within the WEB-INF and META-INF directories, potentially exposing configuration details, credentials, or source code. This information disclosure could aid in further attacks against the Jira instance [1].
Mitigation
Atlassian has fixed this vulnerability in Jira Server and Jira Data Center versions 8.5.11, 8.13.3, and 8.15.0. Users should upgrade to these versions or later. No workarounds have been published [1].
