Multiple vulnerabilities have been reported in Condor, which can be exploited by malicious, local users to gain escalated privileges, by malicious users to bypass certain security restrictions, and by malicious people to disclose sensitive information and potentially compromise a vulnerable system.

1) An error when handling certain parameters within HTTP POST requests can be exploited to submit a job attribute change (e.g. Owner attribute).

2) An error within the filesystem authentication mechanism may result in accepting directories with insecure permissions (e.g. chmod 777) subsequently allowing job creation with different privileges.

3) An error in startd related to the GIVE_REQUEST_AD handler can be exploited to disclose the ClaimId and control or start jobs.

Successful exploitation of this vulnerability requires knowing the PID of a process.

4) An error when handling job abort requests due to permissions validation relying on WRITE authorization only can be exploited to abort an idle job.

The vulnerabilities are reported in versions prior to 7.8.4.

Solution
Update to version 7.8.4.
