CVE-2019-10239 in RunAsSpc
Summary
by MITRE
Robotronic RunAsSpc 3.7.0.0 protects stored credentials insufficiently, which allows locally authenticated attackers (under the same user context) to obtain cleartext credentials of the stored account.

The vulnerability identified as CVE-2019-10239 affects Robotronic RunAsSpc version 3.7.0.0, a credential management utility designed to store and execute operations under different user accounts. This flaw represents a critical security weakness in how the application handles credential storage and retrieval processes. The vulnerability specifically targets the protection mechanisms employed by the software when storing user credentials, creating an exploitable condition that undermines the fundamental security assumptions of credential management systems.
The technical implementation of this vulnerability stems from inadequate cryptographic protection of stored credentials within the RunAsSpc application. When users configure the software to store account credentials for automated operations, the system fails to properly encrypt or obfuscate these sensitive data elements. This insufficient protection mechanism allows local attackers who have already established authentication under the same user context to directly access the credential storage components. The flaw operates at the application level where the software does not implement proper access controls or encryption protocols for sensitive data at rest, creating a direct pathway for credential exposure.
From an operational impact perspective, this vulnerability significantly weakens the security posture of systems utilizing Robotronic RunAsSpc. Local attackers with legitimate user access can exploit this weakness to extract cleartext credentials, potentially enabling privilege escalation attacks or lateral movement within the network. The vulnerability essentially nullifies the security benefits of using credential management tools, as the stored credentials become accessible to any user with local system access. This creates a dangerous scenario where legitimate user credentials can be harvested without requiring additional authentication mechanisms or bypassing network-level security controls.
The vulnerability aligns with CWE-312, which specifically addresses the exposure of sensitive information through improper handling of stored credentials. This weakness represents a failure in secure credential storage practices and violates fundamental security principles for protecting authentication data. From an ATT&CK framework perspective, this vulnerability maps to techniques involving credential access and privilege escalation, particularly T1555.003 for credentials from password stores and T1078 for valid accounts. The attack vector requires local system access but provides attackers with immediate access to stored credentials, making it particularly dangerous in environments where local access is commonly granted to multiple users or where system isolation is insufficient.
Organizations should immediately implement mitigations including updating to patched versions of Robotronic RunAsSpc, implementing additional access controls for credential storage locations, and conducting thorough audits of all credential management tools in use. System administrators should also consider restricting local access privileges where possible and implementing monitoring for unauthorized access attempts to credential storage areas. The remediation process should include comprehensive credential rotation for all accounts managed through the vulnerable software, as well as enhanced security awareness training for users who may inadvertently expose their credentials through improper system usage patterns.
