CVE-2019-0307 in Solution Manager
Summary
by MITRE
Diagnostics Agent in Solution Manager, version 7.2, stores several credentials such as SLD user connection as well as Solman user communication in the SAP Secure Storage file which is not encrypted by default. By decoding these credentials, an attacker with admin privileges could gain access to the entire configuration, but no system sensitive information can be gained.

The vulnerability identified as CVE-2019-0307 resides within the Diagnostics Agent component of SAP Solution Manager version 7.2, specifically targeting the SAP Secure Storage mechanism that handles credential management. This flaw represents a significant security weakness in SAP's credential storage architecture, as it exposes sensitive authentication information to potential attackers who possess administrative privileges on the system. The vulnerability manifests when the Diagnostics Agent stores critical credentials including SLD user connection details and Solman user communication parameters within the SAP Secure Storage file without implementing default encryption mechanisms.
The technical implementation of this vulnerability stems from the improper handling of sensitive data within SAP's secure storage framework. When credentials are stored in the SAP Secure Storage file, they are not encrypted by default, creating a scenario where any attacker with administrative access to the system can potentially decode and extract these stored credentials. This weakness directly violates fundamental security principles regarding the protection of sensitive information and represents a clear deviation from industry standards for secure credential storage. The vulnerability aligns with CWE-312, which specifically addresses the exposure of sensitive information through improper encryption or lack thereof, and can be categorized under the broader category of credential management flaws.
The operational impact of this vulnerability extends beyond simple credential exposure, as it provides attackers with elevated privileges that could enable them to access the complete configuration of the Solution Manager system. While the vulnerability does not directly expose system-sensitive information, the ability to decode stored credentials allows attackers to potentially escalate their privileges and gain deeper access to the system's configuration parameters. This access could enable attackers to manipulate system settings, modify configurations, or potentially establish persistence mechanisms within the Solution Manager environment. The attack surface is particularly concerning because it targets the administrative capabilities of the system, potentially allowing attackers to compromise the integrity of the entire Solution Manager infrastructure.
Mitigation strategies for CVE-2019-0307 should focus on implementing proper encryption mechanisms for stored credentials within the SAP Secure Storage file. Organizations should ensure that all sensitive information stored in SAP Secure Storage is encrypted by default, and administrators must verify that encryption is properly configured and functioning. The implementation of additional access controls and monitoring mechanisms around credential storage locations is essential to detect unauthorized access attempts. Furthermore, organizations should consider implementing regular security assessments of their SAP environments to identify and remediate similar credential storage vulnerabilities. This vulnerability also highlights the importance of adhering to the principle of least privilege and implementing comprehensive credential management practices that align with established security frameworks and best practices for secure system administration.
