| CVE | Summary | Source | Max CVSS | EPSS % | Published | Updated |
|---|---|---|---|---|---|---|
| CVE-2019-25030 | In Versa Director, Versa Analytics and VOS, Passwords are not hashed using an adaptive cryptographic hash function or key derivation function prior to storage. Popular hashing algorithms based on the Merkle-Damgardconstruction (such as MD5 and SHA-1) alone are insufficient in thwarting password cracking. Attackers can generate and use precomputed hashes for all possible password character combinations (commonly referred to as "rainbow tables") relatively quickly. The use of adaptive hashing algo | [email protected] | 5.5 | 0.22% | 2021-05-26 | 2026-06-16 |
| CVE-2018-16499 | In VOS compromised, an attacker at network endpoints can possibly view communications between an unsuspecting user and the service using man-in-the-middle attacks. Usage of unapproved SSH encryption protocols or cipher suites also violates the Data Protection TSR (Technical Security Requirements). | [email protected] | 5.9 | 0.31% | 2021-05-26 | 2026-06-16 |
| CVE-2018-16495 | In VOS user session identifier (authentication token) is issued to the browser prior to authentication but is not changed after the user successfully logs into the application. Failing to issue a new session ID following a successful login introduces the possibility for an attacker to set up a trap session on the device the victim is likely to login with. | [email protected] | 8.8 | 0.91% | 2021-05-26 | 2026-06-16 |
| CVE-2018-16494 | In VOS and overly permissive "umask" may allow for authorized users of the server to gain unauthorized access through insecure file permissions that can result in an arbitrary read, write, or execution of newly created files and directories. Insecure umask setting was present throughout the Versa servers. | [email protected] | 8.8 | 1.92% | 2021-05-26 | 2026-06-16 |
