Bizmanager: Improper Authentication
CVE-2022-35898 is a critical-severity improper authentication vulnerability in Bizmanager from OpenText, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 16.6.0.1 as the first without the flaw, so updating Bizmanager to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.64% chance of exploitation within 30 days, higher than 51% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Bizmanager to 16.6.0.1 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
