CVE-2023-6719Network attack vector

Session takeover via reflected JavaScript payload injection

Published Dec 13, 2023 · Updated Aug 2, 2024

Reflected XSS in Repox 2.3.7 and earlier allows remote attackers to take control of a user's session through a crafted JavaScript payload. INCIBE has not published the affected request parameter or the output-rendering locus that handles the untrusted payload incorrectly. Exploitation requires the targeted user to interact with the attacker-supplied payload; the reported consequence is control of that user's session.
