CWE-918

Description

IPv4-mapped IPv6 addresses did not get recognized as "local" by the code and a connection attempt is made. Attackers with access to user accounts could use this to bypass existing deny-list functionality and trigger requests to restricted network infrastructure to gain insight about topology and running services. We now respect possible IPV4-mapped IPv6 addresses when checking if contained in a deny-list. No publicly available exploits are known.

Affected configurations

• open-xchange open-xchange appsuite backend (< 7.10.6) • open-xchange open-xchange appsuite backend (>= 8.0.0 < 8.11.0) • open-xchange open-xchange appsuite backend 7.10.6
