CVE-2025-55269 is a weak password policy flaw in HCL Aftermarket DPC, scored CVSS 4.2 (medium). It makes guessing and brute force attacks on user accounts easier. HCL's knowledge base article names the corrected build, so confirm it, update, and reset weak passwords.
What's affected
The NVD record names HCL Aftermarket DPC and gives no version ranges. The same article covers CVE-2025-55261, CVE-2025-55267 and CVE-2025-55270.
The HCL support portal did not return article text when I fetched it, so this guide relies on the NVD record. Read the article itself for the fixed version.
How to check if you're exposed
HCL publishes the affected and fixed builds for Aftermarket DPC in its knowledge base article, and that article is the authority. I could not read its text when preparing this guide, so I will not state a fixed version here.
- Find the build you run. The admin or about page of the product usually shows it, and so does your deployment record.
- Open the HCL article listed under Sources and compare your build with its list of affected and fixed builds.
- If the article lists a fix and you are behind it, you are exposed to the issue described here. If your build is not named, ask HCL support to confirm in writing.
Look at the sign in page as an attacker would. Does it lock accounts or slow down after repeated failures, and does it accept short passwords? If the answers are no, add controls in front of it while you wait for the update.
What to do now
- Find every Aftermarket DPC instance and its build.
- Update to the build HCL names.
- Reset passwords that were set under the old policy, prioritising administrators and partner accounts.
- Add rate limiting or lockout at a gateway or web application firewall if the product does not provide it.
- Enable multi factor sign in or single sign on where available.
Why it matters
The class is CWE-521, weak password requirements. The record notes that attackers can guess weak passwords or use brute force. Both rely on cheap, repeated attempts, so the controls that matter most are a strong policy, lockout or throttling, and a second factor.
This CVE is rated medium, but it matters most when paired with the access control issue CVE-2025-55261 from the same article. A guessed password plus missing function level checks is the kind of chain that turns a small login into a large breach.
Quick check
Is a stronger policy enough on its own?
No. Policy only shapes new passwords. Throttling and a second factor protect the passwords you already have.
