Affected Software
Remediation
Recommended actions to resolve this vulnerability, in priority order.
- Remove
Remove
csetup (SGI IRIX)from your environment.If csetup is not required for operations, uninstall or remove the csetup binary from IRIX systems to eliminate the ability to create or overwrite arbitrary files.
- Configuration
Remove the setuid bit from the csetup binary and restrict its executable permissions so only trusted administrative accounts can run it.
csetup (SGI IRIX) setuid / executable permissions = remove setuid; restrict execution to administrative users - Compensating control
Limit access to systems running SGI IRIX to trusted administrators only (via host ACLs, jump hosts, or network isolation) and enforce least-privilege on accounts to prevent untrusted users from executing csetup.
- Operational
Audit systems for unauthorized or unexpected file creations/overwrites, restore impacted files from known-good backups, and investigate to determine whether sensitive files or credentials were modified; if so, remediate (for example, replace or rotate affected credentials).
