CVE-2021-3144 is a critical vulnerability affecting SaltStack Salt versions prior to 3002.5. This vulnerability allows eauth tokens to be reused once after they have expired, potentially enabling unauthorized command execution against the Salt master or its minions. The CVSS score for this vulnerability is 9.1, indicating a critical level of severity that requires immediate attention.
Risk to organizations includes significant confidentiality and integrity impacts due to the potential for unauthorized access and control over systems using SaltStack Salt. Given the critical nature of this vulnerability, organizations must act swiftly to address it.
Currently, there are no known exploits or public proof of concepts available for this vulnerability, but the potential for exploitation remains high. Organizations should prioritize patching immediately to safeguard their environments from potential attacks.
Immediate patching is crucial as the vulnerability could be leveraged by attackers to execute commands in a compromised environment, further emphasizing the need for timely remediation.
Vulnerability Details
In SaltStack Salt before 3002.5, eauth tokens can be used once after expiration. This vulnerability allows an attacker to execute commands against the Salt master or its minions if they possess the expired eauth token.
The CVSS score of 9.1 categorizes this vulnerability as critical, indicating a high likelihood of exploitation. The vulnerability is classified under CWE-613, which pertains to the improper handling of expired tokens.
Affected systems include various versions of SaltStack Salt, Fedora, and Debian Linux, specifically those versions prior to the patched release.
Technical Analysis
The root cause of CVE-2021-3144 is the reuse of expired eauth tokens, which should not be permitted. The attack vector for this vulnerability is network-based, requiring low complexity and no privileges or user interaction. This means that an attacker can exploit this vulnerability without needing any prior access or special permissions.
The vulnerability has a high impact on confidentiality and integrity, as it allows unauthorized access and control over systems, while availability is not affected.
Risk & Impact Analysis
The real-world risk associated with CVE-2021-3144 is significant, especially in environments where SaltStack Salt is deployed. Attackers may leverage this vulnerability to gain unauthorized access to sensitive systems, potentially leading to data breaches and operational disruptions.
Organizations using affected versions of SaltStack Salt must understand the potential blast radius. If exploited, an attacker could gain control over not only the Salt master but also all connected minions, leading to widespread impact across the network.
Given the critical CVSS score and the fact that this vulnerability is not part of the Known Exploited Vulnerabilities (KEV) catalog, organizations should address this issue in their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions include SaltStack Salt before 3002.5, various versions of Fedora, and Debian Linux versions 9.0, 10.0, and 11.0. Users of these systems should upgrade to the latest patched versions to mitigate this vulnerability.
Mitigation & Remediation
Organizations using affected systems should prioritize applying patches provided by the vendors. The patched versions of SaltStack Salt are available for download, and users should ensure that they are running versions 3002.5 or above.
In addition to patching, organizations should consider implementing additional network controls and monitoring to detect any unauthorized command executions that may attempt to exploit this vulnerability.
For detailed guidance on security testing and remediation strategies, organizations may refer to the penetration testing services that can help identify vulnerabilities in their environments.
Detection Guidance
Organizations should monitor logs for any unusual activities related to eauth tokens and unauthorized command executions. Behavioral anomalies, such as unexpected command patterns or access attempts from unusual sources, should be flagged for investigation.
Network signatures that indicate the use of expired tokens or unauthorized access attempts should also be implemented to enhance detection capabilities.
AppSecure Threat Intelligence Insight
