Bug#1078160: bullseye-pu: package ocsinventory-server/2.8.1+dfsg1-1+deb11u1

[Bastien Roucariès]

Package: release.debian.org
Severity: normal
Tags: bullseye
X-Debbugs-Cc: ocsinventory-server at packages.debian.org
Control: affects -1 + src:ocsinventory-server
User: release.debian.org at packages.debian.org
Usertags: pu

[ Reason ]
CVE-2022-39369

[ Impact ]
Service Hostname Discovery Exploitation

The phpCAS library uses HTTP headers to determine the service URL used to
validate tickets. This allows an attacker to control the host header and use a
valid ticket granted for any authorized service in the same SSO realm (CAS
server) to authenticate to the service protected by phpCAS.
Depending on the settings of the CAS server service registry in worst case this
may be any other service URL (if the allowed URLs are configured to
"^(https)://.*") or may be strictly limited to known and authorized services in
the same SSO federation if proper URL service validation is applied.

This vulnerability may allow an attacker to gain access to a victim's account
on a vulnerable CASified service without victim's knowledge, when the victim
visits attacker's website while being logged in to the same CAS server.
