Chinese hackers are actively exploiting a critical vulnerability in SAP NetWeaver known as CVE-2025-31324, a remote code execution (RCE) flaw with a maximum CVSS score of 10.0. This vulnerability, identified by leading threat researchers at Forescout Vedere Labs and confirmed by Onapsis and Mandiant, allows attackers to upload malicious web shells through the ‘/developmentserver/metadatauploader’ endpoint. With the potential to impact multiple industries worldwide, this exploit is particularly dangerous for organizations relying on SAP for mission-critical operations.
What Is SAP CVE-2025-31324?
SAP CVE-2025-31324 is a severe flaw in SAP NetWeaver that enables remote code execution by exploiting a weakness in the metadata uploader endpoint. The vulnerability, with its perfect CVSS score, makes it an attractive target for malicious actors seeking to infiltrate enterprise systems. Once exploited, attackers can drop web shells, deploy further malware, and gain persistent access to the compromised network.
How Are Chinese Hackers Exploiting This Flaw?
Recent reports by Forescout Vedere Labs have revealed that a China-linked threat actor, known as Chaya_004, is actively weaponizing this vulnerability to conduct widespread attacks. The group has been seen deploying various sophisticated tools, including:
- Golang SuperShell: An advanced reverse shell tool that enables remote control of compromised systems. More details about SuperShell can be found on its GitHub repository.
- Cobalt Strike: A well-known post-exploitation framework.
- SoftEther VPN: A tool used for creating secure communications channels.
- Asset Reconnaissance Lighthouse (ARL): A tool for network scanning and information gathering.
Researchers have tracked exploitation back to early 2025, with significant malicious activity recorded between March 14 and March 31, 2025. Additional reconnaissance activities were observed even earlier, indicating a prolonged and well-planned campaign.
Understanding Golang SuperShell
Golang SuperShell is the tool of choice for the threat actor due to its effectiveness as a reverse shell. Hosted on the IP address 47.97.42[.]177, it provides the attackers with a robust mechanism to take control of affected systems. This innovative tool, written in Golang, demonstrates both efficiency and potency in bypassing traditional security measures, and its deployment underscores the innovative tactics employed by modern cybercriminals.
Industries Most at Risk
The exploitation of SAP CVE-2025-31324 has widespread implications as it affects several industries globally. According to reports from Onapsis, industries such as energy, manufacturing, pharmaceuticals, media, and government organizations are being targeted. The vulnerabilities in SAP systems can lead to severe operational disruptions and financial losses, making it imperative for organizations across all sectors to address these potential threats immediately.
Mitigation Strategies: How to Protect Your SAP Systems
To defend against this emerging threat, cybersecurity professionals and SAP administrators should consider the following strategies:
- Immediate Patching: Apply the latest SAP security patches as soon as they become available to remediate the vulnerability.
- Endpoint Hardening: Restrict access to the metadata uploader endpoint and disable services such as Visual Composer if they are not in use.
- Continuous Monitoring: Implement robust monitoring solutions to detect unusual activity and web shell deployment. Regularly check for anomalous network connections, especially to IP addresses like 47.97.42[.]177.
- Layered Security Measures: Use firewalls, intrusion detection systems, and endpoint protection tools to enhance overall security posture.
- Threat Intelligence Integration: Stay informed about the latest exploits and vulnerabilities by following trusted sources. For instance, The Hacker News provides timely updates on these threats.
