Description

This security bulletin contains information about 1 vulnerability.


1) Use of Less Trusted Source (CVE-ID: N/A)

CWE-ID: CWE-348 - Use of Less Trusted Source

CVSSv4: 8.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to bypass IP-based access restrictions and disclose sensitive information.

The vulnerability exists due to use of a less trusted source in the login handler and IP handling logic when processing the `CF-Connecting-IP` header from client requests. A remote attacker can send a specially crafted request with a spoofed `CF-Connecting-IP` header to bypass IP-based access restrictions and disclose sensitive information.

The issue can bypass fail2ban brute-force protections and poison authentication audit logs by recording the spoofed address instead of the real client IP.
