- Summary
- Mojolicious versions from 4.59 before 9.48 for Perl expose a stable representation of the session CSRF token to a BREACH compression oracle
- Details
-
Mojolicious versions from 4.59 before 9.48 for Perl expose a stable representation of the session CSRF token to a BREACH compression oracle.
csrftoken generates and caches one token per session and returns the same value on every call, and csrffield places that value in a hidden
csrf_tokeninput. When a response carrying the token also echoes attacker-controlled input and is gzip-compressed, the chosen values and the resulting compressed lengths form a BREACH oracle.An attacker able to query it can recover the token and pass csrf_protect validation.
