CVE-2007-2233: cosign-bin/cosign.cgi in Cosign 2.0.2 and earlier allows remote authenticated users to perform unauthorized...

Security readout for executives and security teams

This flaw affects Cosign SSO 2.0.2 and earlier. An already authenticated remote user could make the SSO component treat actions as another chosen user. For organizations that still run this legacy SSO software, the business risk is account impersonation across protected services. Exposure is likely limited to environments still running Cosign 2.0.2 or earlier with cosign-bin/cosign.cgi reachable to authenticated users. The source bundle does not identify specific downstream products or package names. Treat as high priority only if Cosign is still present. Legacy SSO impersonation flaws can affect multiple protected applications through one authentication layer, but evidence here does not support active exploitation claims. Mitigation focus: Inventory Cosign deployments and identify any version 2.0.2 or earlier.; Check University of Michigan Cosign guidance for the fixed release or supported workaround.; Restrict access to cosign-bin/cosign.cgi where operationally possible..
