CVE-1999-1324: HP Openvms Vax

Critical severity, CVSS 9.8. EPSS: 3.1% chance of exploitation in the next 30 days.

VAXstations running Open VMS 5.3 through 5.5-2 with VMS DECwindows or MOTIF do not properly disable access to user accounts that exceed the break-in limit threshold for failed login attempts, which makes it easier for attackers to conduct brute force password guessing.

Affected products

• HP Openvms Vax: from 5.3, up to and including 5.5.2
