DescriptionNVD
PowSyBl (Power System Blocks) is a framework to build power system oriented software. In com.powsybl:powsybl-iidm-criteria versions 6.3.0 to before 6.7.2 and com.powsybl:powsybl-contingency-api versions 5.0.0 to before 6.3.0, there is a a potential polynomial Regular Expression Denial of Service (ReDoS) vulnerability in the RegexCriterion class. This class compiles and evaluates an unvalidated, user-supplied regular expression against the identifier of an Identifiable object via Pattern.compile(regex).matcher(id).find(). If successfully exploited, a malicious actor can cause significant CPU exhaustion through repeated or recursive filter(...) calls - especially if performed over large network models or filtering operations. This issue has been patched in com.powsybl:powsybl-iidm-criteria 6.7.2.

Technical ContextAI
A denial of service vulnerability allows an attacker to disrupt the normal functioning of a system, making it unavailable to legitimate users. This vulnerability is classified as Inefficient Regular Expression Complexity (ReDoS) (CWE-1333).
RemediationAI
Implement rate limiting and input validation. Use timeout mechanisms for resource-intensive operations. Deploy DDoS protection where applicable.
