CVE-2024-41766 is a denial-of-service vulnerability affecting IBM Engineering Lifecycle Optimization - Publishing versions 7.0.2 and 7.0.3. The flaw, classified under CWE-1333, arises from the use of a complex regular expression that can be exploited to consume excessive resources, leading to service disruption. It has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating high severity due to its potential for significant availability impact without requiring authentication or user interaction.
A remote attacker can exploit this vulnerability over the network with low complexity and no privileges by sending a specially crafted request containing a complex regular expression. Successful exploitation results in a denial of service, potentially crashing the affected service or rendering it unresponsive, though it does not enable data exfiltration, modification, or privilege escalation.
IBM has published a security advisory at https://www.ibm.com/support/pages/node/7180203 providing details on the vulnerability and available patches or workarounds for mitigation. Security practitioners should review the advisory for version-specific remediation steps to protect affected deployments.

Developer testing and evaluation can discover inefficient regex patterns via performance or static analysis.
Development standards and tools can require safe regex construction and forbid known exponential patterns.
Denial-of-service protections limit resource exhaustion caused by expensive regex evaluation.
Input validation can constrain data that would otherwise trigger worst-case regex complexity.

Security testing can detect and reject regex patterns with exponential worst-case complexity.
Secure development lifecycle mandates review of algorithmic efficiency, directly addressing ReDoS-prone regex.
Application security requirements can specify input-validation rules that limit regex complexity.
Secure architecture principles encourage avoidance of computationally expensive constructs such as catastrophic backtracking.
Secure coding standards explicitly prohibit or limit the use of inefficient regular expressions.
