CVE-2025-31998 is a low severity (CVSS 3.5) flaw in HCL Unica Centralized Offer Management. Unhandled exceptions expose sensitive information. HCL bulletin KB0124422 lists the fixed version, so read it, apply the update, and make sure error pages reveal nothing internal.
What's affected
The NVD record names HCL Unica Centralized Offer Management. It says poorly handled exceptions expose sensitive information, and that an attacker could use that information to prepare targeted attacks, such as remote code execution or denial of service. The weakness classes are CWE-209 (generation of an error message containing sensitive information) and CWE-703 (improper check or handling of exceptional conditions).
The CVSS 3.1 vector is CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:N. A low privilege account and some user interaction are needed, and only confidentiality is affected, at a low level.
The affected and fixed versions are in the HCL bulletin, which did not render for a plain fetch. The same bulletin also covers CVE-2025-31993.
How to check if you're exposed
- Find your Unica Centralized Offer Management release.
- Compare it with the affected versions in bulletin KB0124422.
- Trigger a harmless error in a test environment, for example by requesting a page that does not exist, and look at what the response shows. Stack traces, file paths, library names and versions are the kind of detail the record is about.
- Check the application logs and any front end proxy to see whether detailed errors reach the browser.
Do not run this check against a production system you do not own.
What to do now
- Apply the HCL update named in the bulletin.
- Configure generic error pages so users see a short message and a reference id, while the full trace goes to the log only.
- Limit who can log in with a low privilege account, and review the list.
- Treat leaked version details as a hint to attackers and keep patches current on everything else the stack depends on.
The free in-browser dependency scan takes a manifest or lockfile and lists known CVEs for the packages in it, and the Gold directory lets you look up a CVE by id.
Why it matters
Error messages are written for developers. When they reach a user, they can reveal paths, framework versions and internal names. None of that is a break in itself, but it saves an attacker time, and it tells them which known vulnerabilities to try.
The record's own wording says the leaked detail could help someone choose a targeted attack. That is why a low rated issue still belongs in a normal patch cycle.
Quick check
Does this let someone take over the system?
Not by itself. The impact is limited to information exposure, though the record says the details could help plan later attacks.
Where is the fixed version?
In HCL bulletin KB0124422. The NVD record does not state it.
