Unified PAM: Use of Weak Credentials
CVE-2025-6737 is a high-severity use of weak credentials vulnerability in Unified PAM from Securden, with a CVSS 3.1 base score of 7.2 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 11.3.1 as the first without the flaw, so updating Unified PAM to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.27% 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 Unified PAM to 11.3.1 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
Securden’s Unified PAM Remote Vendor Gateway access portal shares infrastructure and access tokens across multiple tenants. A malicious actor can obtain authentication material and access the gateway server with low-privilege permissions.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Use of Weak Credentials
The product uses weak credentials (such as a default key or hard-coded password) that can be calculated, derived, reused, or guessed by an attacker.
How developers prevent this class of flaw
- When the user changes or sets a password, check the password against a database of already compromised or breached passwords. These passwords are likely to be used in password guessing attacks.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
