CVSS: 9.0EPSS: 0%CPEs: 1EXPL: 0CVE-2024-29021 – SSRF into Sandbox Escape through Unsafe Default Configuration
https://notcve.org/view.php?id=CVE-2024-29021
Judge0 is an open-source online code execution system. The default configuration of Judge0 leaves the service vulnerable to a sandbox escape via Server Side Request Forgery (SSRF). This allows an attacker with sufficient access to the Judge0 API to obtain unsandboxed code execution as root on the target machine. This vulnerability is fixed in 1.13.1. Judge0 es un sistema de ejecución de código en línea de código abierto. • https://github.com/judge0/judge0/blob/ad66f77b131dbbebf2b9ff8083dca9a68680b3e5/app/jobs/isolate_job.rb#L203-L230 https://github.com/judge0/judge0/security/advisories/GHSA-q7vg-26pg-v5hr • CWE-918: Server-Side Request Forgery (SSRF) CWE-1393: Use of Default Password •
CVSS: 10.0EPSS: 0%CPEs: 1EXPL: 0CVE-2024-28189 – Judge0 vulnerable to Sandbox Escape Patch Bypass via chown running on Symbolic Link
https://notcve.org/view.php?id=CVE-2024-28189
Judge0 is an open-source online code execution system. The application uses the UNIX chown command on an untrusted file within the sandbox. An attacker can abuse this by creating a symbolic link (symlink) to a file outside the sandbox, allowing the attacker to run chown on arbitrary files outside of the sandbox. This vulnerability is not impactful on it's own, but it can be used to bypass the patch for CVE-2024-28185 and obtain a complete sandbox escape. This vulnerability is fixed in 1.13.1. • https://github.com/judge0/judge0/blob/v1.13.0/app/jobs/isolate_job.rb#L232 https://github.com/judge0/judge0/commit/f3b8547b3b67863e4ea0ded3adcb963add56addd https://github.com/judge0/judge0/security/advisories/GHSA-3xpw-36v7-2cmg https://github.com/judge0/judge0/security/advisories/GHSA-h9g2-45c8-89cf https://tantosec.com/blog/judge0 • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-61: UNIX Symbolic Link (Symlink) Following •
CVSS: 10.0EPSS: 0%CPEs: 1EXPL: 0CVE-2024-28185 – Judge0 vulnerable to Sandbox Escape via Symbolic Link
https://notcve.org/view.php?id=CVE-2024-28185
Judge0 is an open-source online code execution system. The application does not account for symlinks placed inside the sandbox directory, which can be leveraged by an attacker to write to arbitrary files and gain code execution outside of the sandbox. When executing a submission, Judge0 writes a `run_script` to the sandbox directory. The security issue is that an attacker can create a symbolic link (symlink) at the path `run_script` before this code is executed, resulting in the `f.write` writing to an arbitrary file on the unsandboxed system. An attacker can leverage this vulnerability to overwrite scripts on the system and gain code execution outside of the sandbox. • https://github.com/judge0/judge0/blob/v1.13.0/app/jobs/isolate_job.rb#L197-L201 https://github.com/judge0/judge0/commit/846d5839026161bb299b7a35fd3b2afb107992fc https://github.com/judge0/judge0/security/advisories/GHSA-h9g2-45c8-89cf • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-61: UNIX Symbolic Link (Symlink) Following •
