Published: 20 August 2023
Summary
CVE-2023-4451 is a medium-severity Cross-site Scripting (CWE-79) vulnerability in Agentejo Cockpit. Its CVSS base score is 6.1 (Medium).
Operationally, ranked in the top 1.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2023-4451 is a reflected cross-site scripting vulnerability (CWE-79) affecting the Cockpit content management system in the cockpit-hq/cockpit repository prior to version 2.6.4. The flaw carries a CVSS 3.1 score of 6.1 with a network attack vector, low complexity, no required privileges, and required user interaction, resulting in limited impacts to confidentiality and integrity under a changed scope.
An unauthenticated remote attacker can exploit the issue by crafting a malicious URL that, when visited by a target user, executes arbitrary script within the Cockpit application context. Successful exploitation allows the attacker to perform actions such as data exfiltration or unauthorized operations on behalf of the victim user.
Public references point to a fix committed in the upstream repository that resolves the reflected XSS vector, indicating that updating to Cockpit 2.6.4 or later is the primary mitigation. The associated EPSS score reached a peak of 0.6361 with a current value of 0.5674.
