tnms: Cleartext Storage of Sensitive Information
CVE-2024-25661 is a high-severity cleartext storage of sensitive information vulnerability in tnms from Infinera, with a CVSS 3.1 base score of 7.7 out of 10. It can be exploited with local access to the system by an attacker with administrator privileges, but only if a user takes part, for example by opening a link or file. Affected tnms versions: 19.10.3. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.13% 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
- Check which version of tnms you run against the affected versions below, and install the vendor's latest release.
- Because the attack needs a user to take part, warn users about unexpected links and files related to this product until it is patched.

The underlying weakness: Cleartext Storage of Sensitive Information
The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.
How developers prevent this class of flaw
- When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to encrypt the data at rest.
- In some systems/environments such as cloud, the use of double encryption (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
