CVE-2025-30012: SAP SRM RCE Vulnerability

CVE-2025-30012 Overview

CVE-2025-30012 is a critical insecure deserialization vulnerability affecting the Live Auction Cockpit component in SAP Supplier Relationship Management (SRM). The vulnerability exists due to the use of a deprecated Java applet component that improperly handles encoded payload requests. An unauthenticated attacker can exploit this flaw by sending specially crafted malicious requests in a specific encoding format to the vulnerable servlet, which then decodes and deserializes the data without proper validation, ultimately leading to arbitrary OS command execution with SAP Administrator privileges.

Critical Impact

Successful exploitation allows unauthenticated attackers to execute arbitrary operating system commands as SAP Administrator, resulting in complete system compromise with high impact on confidentiality, integrity, and availability.

Affected Products

• SAP Supplier Relationship Management (SRM) version 7.14
• Live Auction Cockpit component utilizing deprecated Java applet

Technical Details for CVE-2025-30012

Vulnerability Analysis

This vulnerability is classified as CWE-502 (Deserialization of Untrusted Data). The Live Auction Cockpit in SAP SRM relies on a deprecated Java applet architecture that processes incoming requests through a servlet. The servlet accepts encoded payloads and performs deserialization operations without adequate validation of the incoming data stream. Because the deserialization process occurs before any security checks, attackers can craft malicious serialized Java objects that, when deserialized, trigger the execution of arbitrary commands on the underlying operating system.

The attack is particularly severe because it requires no authentication, can be executed remotely over the network, and results in command execution with elevated SAP Administrator privileges. This combination of factors creates a direct path from network access to complete system compromise.

Root Cause

The root cause of CVE-2025-30012 lies in the insecure handling of serialized data within the deprecated Java applet component. The servlet responsible for processing requests from the Live Auction Cockpit decodes incoming payloads and passes them directly to Java's deserialization mechanism without implementing proper input validation, allowlisting of expected classes, or other defensive measures. This architectural flaw allows attackers to inject malicious serialized objects that execute arbitrary code during the deserialization process.

Attack Vector

The attack is network-based and requires no user interaction or prior authentication. An attacker can target the vulnerable servlet endpoint by:

1. Identifying an exposed SAP SRM instance with the Live Auction Cockpit component
2. Crafting a malicious serialized Java object containing OS command execution payloads
3. Encoding the payload in the specific format expected by the servlet
4. Sending the malicious request to the vulnerable endpoint
5. Upon receipt, the servlet decodes and deserializes the payload, triggering command execution

The exploitation leverages common Java deserialization gadget chains to achieve arbitrary command execution. Since the servlet runs with SAP Administrator privileges, all executed commands inherit these elevated permissions, allowing attackers to fully compromise the SAP system and potentially pivot to other connected systems.

Detection Methods for CVE-2025-30012

Indicators of Compromise

• Unusual or unexpected HTTP/HTTPS requests to the Live Auction Cockpit servlet endpoints
• Presence of serialized Java object signatures in web server request logs (look for AC ED 00 05 magic bytes in encoded form)
• Unexpected process spawning from the SAP application server context
• Anomalous outbound network connections originating from SAP SRM servers

Detection Strategies

• Monitor web application logs for requests containing suspicious encoded payloads targeting auction-related endpoints
• Implement network intrusion detection rules to identify Java serialization attack patterns
• Deploy application-level logging to capture deserialization events and their sources
• Use endpoint detection and response (EDR) solutions to monitor for command execution originating from Java processes

Monitoring Recommendations

• Enable verbose logging on SAP SRM web server components and forward logs to SIEM for analysis
• Configure alerts for any shell command execution initiated by the SAP application context
• Monitor for reconnaissance activity targeting SAP SRM instances on the network
• Implement baseline monitoring for normal SAP SRM traffic patterns to detect anomalies

How to Mitigate CVE-2025-30012

Immediate Actions Required

• Apply the security patch detailed in SAP Note #3578900 immediately
• If patching is not immediately possible, disable or restrict access to the Live Auction Cockpit component
• Implement network segmentation to limit exposure of SAP SRM servers to untrusted networks
• Review access logs for any signs of prior exploitation attempts

Patch Information

SAP has released an official security patch addressing this vulnerability. Organizations should review and apply SAP Note #3578900 as part of their remediation efforts. Additional details are available through the SAP Security Patch Day Announcement. The patch addresses the insecure deserialization issue by implementing proper input validation and removing reliance on the deprecated Java applet component.

Workarounds

• Disable the Live Auction Cockpit component if it is not business-critical until the patch can be applied
• Implement web application firewall (WAF) rules to block requests containing Java serialization signatures
• Restrict network access to SAP SRM servers using firewall rules, limiting connectivity to trusted IP ranges only
• Consider implementing Java deserialization filters at the JVM level to block dangerous gadget chains

Organizations should prioritize patching as the primary remediation method, as workarounds may not provide complete protection against all exploitation techniques.
