CVE-2024-48920 — PutongOJ is online judging software
PutongOJ is online judging software. Prior to version 2.1.0-beta.1, unprivileged users can escalate privileges by constructing requests. This can lead to unauthorized access, enabling users to perform admin-level operations, potentially compromising sensitive data and system integrity. This problem has been fixed in v2.1.0.beta.1. As a workaround, one may apply the patch from commit `211dfe9` manually.

Matched remediation archetype
Authentication bypass and missing authentication
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
- Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
- Review session, token, credential, and proxy trust configuration without attempting account takeover.
Remediate safely
- Apply the supported fix and centralize fail-closed authentication before protected request handling.
- Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
- Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
