CVE-2019-10136: Red Hat Satellite

Medium severity, CVSS 4.3. EPSS: 0.6% chance of exploitation in the next 30 days.

It was found that Spacewalk, all versions through 2.9, did not safely compute client token checksums. An attacker with a valid, but expired, authenticated set of headers could move some digits around, artificially extending the session validity without modifying the checksum.

Affected products

• Red Hat Satellite: version 5.8 only
• Red Hat Spacewalk: up to and including 2.9
