CVE-2020-6364 in Solution Manager
Summary
by MITRE • 10/15/2020
SAP Solution Manager and SAP Focused Run (update provided in WILY_INTRO_ENTERPRISE 9.7, 10.1, 10.5, 10.7), allows an attacker to modify a cookie in a way that OS commands can be executed and potentially gain control over the host running the CA Introscope Enterprise Manager,leading to Code Injection. With this, the attacker is able to read and modify all system files and also impact system availability.

The vulnerability identified as CVE-2020-6364 affects SAP Solution Manager and SAP Focused Run products, specifically within the WILY_INTRO_ENTERPRISE component versions 9.7, 10.1, 10.5, and 10.7. This security flaw represents a critical code injection vulnerability that stems from improper input validation within the cookie handling mechanism of the CA Introscope Enterprise Manager application. The vulnerability allows attackers to manipulate session cookies in a manner that enables arbitrary operating system command execution on the host system where the enterprise manager is deployed. This type of vulnerability falls under the CWE-94 category of "Improper Control of Generation of Code" and specifically relates to CWE-74 which covers "Improper Neutralization of Special Elements in Output Used by a Downstream Component."
The technical exploitation of this vulnerability occurs when an attacker modifies a session cookie value to inject malicious commands that are subsequently executed by the underlying operating system. The attack vector leverages the insecure handling of user-supplied data within the cookie structure, which is then processed without proper sanitization or validation. This allows an attacker to execute arbitrary OS commands with the privileges of the user running the CA Introscope Enterprise Manager process, typically a system-level account with extensive access rights. The implications extend beyond simple command execution as the attacker can read and modify all system files, potentially leading to complete system compromise and unauthorized data access.
From an operational impact perspective, this vulnerability poses a severe threat to enterprise environments utilizing SAP Solution Manager and SAP Focused Run solutions. The ability to execute arbitrary commands on the host system means attackers can establish persistent backdoors, exfiltrate sensitive data, modify system configurations, and disrupt business operations through denial of service conditions. The vulnerability affects system availability as attackers can potentially crash services or corrupt system files, while the confidentiality and integrity of the entire system are compromised. This aligns with the ATT&CK framework's T1059.001 technique for Command and Scripting Interpreter, specifically focusing on the execution of OS commands through vulnerable applications.
Organizations should immediately implement mitigations including applying the official security patches provided by SAP for the affected WILY_INTRO_ENTERPRISE versions, implementing network segmentation to limit access to the affected systems, and monitoring for suspicious cookie modifications in web application logs. Additional defensive measures include implementing web application firewalls to detect and block malicious cookie content, conducting regular security assessments of the SAP environment, and establishing robust access controls to limit who can interact with the vulnerable components. The vulnerability demonstrates the critical importance of proper input validation and the principle of least privilege in enterprise security architectures, particularly for mission-critical applications like enterprise performance management systems.
