Improper certificate validation in Apereo CAS Client 4.1.0 and Jasig CAS Client 3.6.4 allows a man-in-the-middle attacker to intercept Ticket-Granting Tickets (TGTs) by presenting any CA-signed certificate for a hostname matching the client's allowlist. An attacker with a network interception position can then obtain service tickets on behalf of the victim. No active exploitation or public exploit code is confirmed, and EPSS indicates low exploitation probability (0.17%).
Plaintext recovery of webflow conversation state in Apereo CAS (versions 7.3.0 up to but not including 8.0.0-RC6) lets remote unauthenticated attackers decrypt sensitive login-flow data by exploiting AES-GCM nonce reuse. Because the server encrypts client-side webflow execution tokens with a fixed all-zero initialization vector under a single long-lived key, an attacker can harvest multiple tokens from the public login page and apply known-plaintext/keystream-reuse analysis to break confidentiality (and, given GCM's nonce-reuse properties, integrity of the token). Publicly available exploit code exists; the flaw was reported by VulnCheck and carries a CVSS 4.0 base of 9.3, though no CISA KEV listing or EPSS score is provided.
Xerte Online Toolkits 3.14 and earlier contain an unauthenticated arbitrary file upload vulnerability allowing remote code execution with a CVSS score of 9.8. The template import functionality at /website_code/php/import/import.php lacks authentication checks, enabling attackers to upload ZIP archives containing malicious PHP files that are extracted to web-accessible directories. This is a critical severity issue with network-based attack vector requiring no privileges or user interaction, and a proof-of-concept has been published by VulnCheck.
