Concrete CMS below 9.5.0 and below is vulnerable to password change without reauthorization and session-hardening bypass.

Concrete CMS below 9.5.0 and below is vulnerable to password change without reauthorization and session-hardening bypass. The user-profile edit controller passes the entire raw POST array to UserInfo::update() without field whitelisting resulting in password change without requiring the current password  and also resulting in registered users able to disable the per-user-IP-pinning in the session validator which is meant to detect hijacking.  The Concrete CMS security team gave this vulnerability a CVSS v.4.0 score of 5.3 with vector CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N. Thanks 0x4c616e for reporting.

Affected devices contain an incorrect authorization check vulnerability. This could allow an authenticated remote attacker with "guest" role to invoke an internal "do system" command which exceeds their privileges. This command allows the execution of certain low-risk actions, the most critical of which is clearing the local system log.
