Dell BSAFE SSL-J: Improper Locking
CVE-2024-29172 is a high-severity improper locking vulnerability in Dell BSAFE SSL-J from Dell, with a CVSS 3.1 base score of 7.5 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 6.6 as the first without the flaw, so updating Dell BSAFE SSL-J to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.45% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Dell BSAFE SSL-J to 6.6 or a later version.
- Update Bsafe Ssl-j to 6.6 or 7.2.1, whichever matches your release line, or a later version.
- Read the advisory on dell.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
