AI-suggested
- Upgrade all instances of powsybl-core and powsybl-commons to version 6.7.2 or later immediately to apply the official patch that disables unsafe XML external entity processing.
- Implement strict input validation and sanitization on all XML inputs, especially from untrusted or external sources, to prevent malicious payloads.
- Employ XML parsers configured to disable external entity resolution and DTD processing by default, even beyond the patched version, as a defense-in-depth measure.
- Restrict network egress from servers running PowSyBl to limit SSRF attack impact, using firewall rules or network segmentation to prevent unauthorized internal resource access.
- Monitor logs for unusual XML parsing errors or unexpected outbound requests that may indicate exploitation attempts.
- Conduct regular security audits and penetration testing focusing on XML processing components within power system software.
- Educate developers and administrators about secure XML handling practices and the risks of XXE and SSRF vulnerabilities in critical infrastructure software.
Description
PowSyBl (Power System Blocks) is a framework to build power system oriented software. Prior to version 6.7.2, in certain places, powsybl-core XML parsing is vulnerable to an XML external entity (XXE) attack and to a server-side request forgery (SSRF) attack. This allows an attacker to elevate their privileges to read files that they do not have permissions to, including sensitive files on the system. The vulnerable class is com.powsybl.commons.xml.XmlReader which is considered to be untrusted in use cases where untrusted users can submit their XML to the vulnerable methods. This can be a multi-tenant application that hosts many different users perhaps with different privilege levels. This issue has been patched in com.powsybl:powsybl-commons: 6.7.2.
