Published Jul 2, 2019
4.3
MEDIUMCVSS 3.0
EPSS 0.57%
Description
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.
