CVE-2024-41766
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIBM Engineering Lifecycle Optimization - Publishing 7.0.2 and 7.0.3 could allow a remote attacker to cause a denial of service using a complex regular expression.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceIBM Engineering Lifecycle Optimization - Publishing versions 7.0.2 and 7.0.3 contains a Regular Expression Denial of Service (ReDoS) vulnerability. A remote attacker can submit a specially crafted complex regular expression that causes excessive backtracking, leading to CPU exhaustion and service denial.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed version of IBM Engineering Lifecycle Optimization - PublishingCheck the product's version information through the IBM Jazz-based administration console, installation directory metadata, or by querying the application via its /admin or /about endpoint. This varies by deployment but typically uses the IBM Installation Manager or WebSphere/ Liberty administration console.Affected if The installed version is exactly 7.0.2 or 7.0.3
-
Confirm the exact version number matches the affected releasesCompare your identified version against the affected versions. Note that the CVE specifies only versions 7.0.2 and 7.0.3 are affected (exact match).Affected if The version is 7.0.2 or 7.0.3 specifically
-
Identify if the publishing component processes regular expressionsReview the IBM Engineering Lifecycle Optimization Publishing configuration to determine if custom regex patterns or dynamic regex processing is enabled. Check publishing templates, data transformation rules, or any user-supplied regex input fields in the web interface.Affected if Regex processing features or endpoints that accept regex input are exposed or enabled in the publishing module
-
Check for signs of ReDoS exploitation or CPU exhaustionReview application and web server logs for patterns of excessive CPU usage, thread blocking, or timeout errors associated with regex processing requests. Look for repeated requests to endpoints that handle pattern matching.Affected if CPU exhaustion or service degradation is occurring from regex-heavy requests, indicating potential exploitation
You are affected if IBM Engineering Lifecycle Optimization - Publishing version 7.0.2 or 7.0.3 is running and regex processing endpoints are accessible or enabled.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply IBM's security patch when available. In the interim, implement request rate limiting and input validation on endpoints processing regex patterns to mitigate exploitation.
