Analysis of PostgreSQL Zero-Day Vulnerability CVE-2025-1094 and Its Connection to BeyondTrust CVE-2024-12356

2025-02-13

Earlier this morning, Rapid7 disclosed CVE-2025-1094, a new zero-day vulnerability in PostgreSQL’s psql component. This discovery was made by principal researcher Stephen Fewer while analyzing BeyondTrust CVE-2024-12356, a related zero-day bug that has recently gained attention due to its connection to a high-profile attack on the U.S. Treasury Department, attributed to Chinese state-sponsored adversaries.

During Rapid7’s analysis of BeyondTrust Remote Support CVE-2024-12356, it was found that a successful exploit for CVE-2024-12356 required the exploitation of PostgreSQL CVE-2025-1094 to achieve remote code execution. Although CVE-2024-12356 was patched in December 2024, the patch did not address the root cause of the PostgreSQL issue, leaving it as a zero-day flaw until today’s release.
