Summary

Glance through version 0.8.5 has an IP address spoofing vulnerability in the authentication handler. An unauthenticated attacker can bypass brute-force lockout protections by supplying arbitrary values in the X-Forwarded-For header when the server proxied option is enabled. Each login attempt appears to come from a different IP, preventing lockout and allowing unlimited password guessing.

Risk Assessment

An attacker can perform unlimited password guessing attempts, increasing the risk of account compromise.

Recommendation

Update Glance to version 0.8.6 or later, which includes a fix for this vulnerability.

Original NVD description (English source)

Glance through 0.8.5 contains an IP address spoofing vulnerability in the authentication handler that allows unauthenticated attackers to bypass brute-force lockout protections by supplying arbitrary values in the X-Forwarded-For request header when the server proxied option is enabled. Attackers can manipulate the leftmost value of the X-Forwarded-For header to make each login attempt appear to originate from a distinct IP address, preventing the per-IP failed-login counter from reaching the lockout threshold and enabling unlimited credential guessing against the authentication endpoint.
