CVE-2025-48058 Details
Description
PowSyBl (Power System Blocks) is a framework to build power system oriented software. Prior to version 6.7.2, there is a potential polynomial Regular Expression Denial of Service (ReDoS) vulnerability in the PowSyBl's DataSource mechanism. If successfully exploited, a malicious actor can cause significant CPU consumption due to regex backtracking — even with polynomial patterns. This issue has been patched in com.powsybl:powsybl-commons: 6.7.2.
A polynomial Regular Expression Denial-of-Service (ReDoS) vulnerability has been identified in the PowSyBl framework's DataSource mechanism, prior to version 6.7.2. This vulnerability allows a malicious actor to cause significant CPU consumption through regex backtracking, even with polynomial patterns. The issue arises when the 'listNames(String regex)' method is called with an unvalidated user-supplied regular expression, which is then evaluated against a collection of file-like resource names. If an attacker can control both the regex input and the resource names, they can exploit the vulnerability, leading to degraded performance and availability, particularly in multi-tenant environments.
Users can upgrade to PowSyBl version 6.7.2 or later to address this vulnerability.
