Overview<\/strong><\/p>\n

A critical vulnerability has been discovered in Apache Jena, a free and open-source Java framework for building Semantic Web and Linked Data applications, that can potentially lead to system compromise and data leakage. Identified as CVE-2025-50151, this vulnerability has a CVSS severity score of 8.8, which is considered high. The flaw lies in the lack of validation for file access paths in configuration files uploaded<\/a> by administrators. This oversight can have serious implications for the confidentiality and integrity of data<\/a>, as well as system availability, and therefore matters to all users of Apache Jena up to version 5.4.0.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-50151
\nSeverity: High (8.8 CVSS score)
\nAttack Vector: Network
\nPrivileges Required: High (Administrator access)
\nUser Interaction: None
\nImpact: System compromise, data leakage<\/a><\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Apache Jena | Up to 5.4.0<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability arises from the lack of validation of file<\/a> access paths in configuration files uploaded by users with administrative access. This means that an attacker with such access can upload a configuration file<\/a> with a malicious file access path. When this configuration file is used by the system, the application ends up reading or writing data to an unintended and potentially insecure location, leading to data leakage or system<\/a> compromise.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how the vulnerability might be exploited using a maliciously crafted configuration file:<\/a><\/p>\n

POST \/admin\/upload_config HTTP\/1.1\nHost: vulnerable.apachejena.com\nContent-Type: application\/xml\n\n..\/..\/..\/etc\/passwd<\/FileAccessPath>\n...\n<\/Configuration><\/code><\/pre>\n
In the above example, the file access path<\/a> points to a system file (`\/etc\/passwd`), which is outside the intended directory. When this configuration is used, it could potentially read or write to this system file<\/a>, leading to a security breach.<\/p>\n
Mitigation<\/strong><\/p>\n
Apache Jena users are advised to upgrade to version 5.5.0, which includes a fix for this vulnerability. In this version, arbitrary configuration upload<\/a> is not allowed, thereby preventing this issue. If upgrading is not immediately possible, users can apply vendor patches or use a Web Application<\/a> Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation.<\/p>\n","protected":false},"excerpt":{"rendered":"
