CVE-2024-10979 is a high-severity vulnerability identified in PostgreSQL, specifically within its PL/Perl component. The vulnerability arises from incorrect control of environment variables, allowing unprivileged database users to modify sensitive process environment variables such as PATH. This manipulation can pave the way for arbitrary code execution, even when the attacker does not possess a database server operating system user account. The affected versions include PostgreSQL prior to 17.1, 16.5, 15.9, 14.14, 13.17, and 12.21.
Given its CVSS score of 8.8, this vulnerability is classified as high risk. Organizations utilizing affected versions of PostgreSQL should consider the potential impacts on their systems. The vulnerability allows for significant risks, including the possibility of unauthorized access and control over database operations. As the risk to organizations includes potential data breaches and loss of integrity, immediate action is warranted.
Currently, there are no known exploits for this vulnerability, but its exploitability is rated as high. This situation necessitates that organizations prioritize remediation efforts as they develop their security strategies.
Organizations should prioritize patching immediately. Ensuring that systems are updated to the latest versions will mitigate the risks associated with this vulnerability.
Vulnerability Details
The vulnerability allows for arbitrary code execution due to improper controls over environment variables within PostgreSQL's PL/Perl. The detailed CVSS vector string is CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H, indicating that the attack vector is network-based, requiring low complexity and low privileges.
The vulnerability classification includes CWE-15 (Improper Control of Environment Variables) and CWE-610 (Excessive Privilege). The publication date for this vulnerability was November 14, 2024.
Technical Analysis
The root cause of this vulnerability stems from the lack of stringent controls over environment variables in PL/Perl. Attackers can exploit this flaw by changing critical environment variables, which can result in arbitrary code execution.
The attack vector is classified as network-based, meaning an attacker can exploit this vulnerability remotely without needing local access. The complexity of the attack is low, and it requires low privileges to execute, making it a significant risk factor. User interaction is not necessary, further increasing the likelihood of successful exploitation.
The impact on confidentiality, integrity, and availability is rated as high, indicating that successful exploitation could lead to serious consequences for affected organizations.
Risk & Impact Analysis
Organizations leveraging PostgreSQL should assess their deployments for this vulnerability. The ease of exploitation combined with the severe potential impacts on confidentiality, integrity, and availability makes this a critical concern.
The blast radius for this vulnerability can be extensive, particularly in environments where PostgreSQL is integral to application functionality. Given the exploitability of this vulnerability, organizations must act promptly to secure their systems. The urgency for remediation is heightened by its high CVSS score and potential impacts.
Organizations should address in priority patch cycle.

Ransomware Use | No |
Affected Versions
The following versions of PostgreSQL are affected: versions before 17.1, 16.5, 15.9, 14.14, 13.17, and 12.21. Organizations should ensure they upgrade to the latest patched versions to mitigate the vulnerability.
Mitigation & Remediation
To remediate this vulnerability, organizations should apply the latest patches provided by PostgreSQL for their respective versions. Ensure that systems are updated to versions 17.1, 16.5, 15.9, 14.14, 13.17, or 12.21 or later.
In cases where immediate patching is not feasible, consider implementing strict access controls to limit the ability of unprivileged users to alter environment variables. Additionally, organizations may explore options for configuration hardening to minimize exposure.
Monitoring for unusual database activities can also be beneficial. Organizations should validate remediation through penetration testing to ensure that no similar vulnerabilities remain unaddressed.
Detection Guidance
Organizations should monitor logs for any unauthorized changes to environment variables. Behavioral anomalies in database operations may indicate exploitation attempts. Additionally, network signatures related to abnormal access patterns should be implemented to enhance detection capabilities.
AppSecure Threat Intelligence Insight
This vulnerability highlights the importance of securing database environments against unauthorized access and manipulation. The trend towards increasingly sophisticated attacks on database systems necessitates a proactive approach to security.
Security teams should prioritize regular audits and assessments to identify and address potential vulnerabilities. Organizations should ensure their defenses are robust and capable of responding to emerging threats. For further strategic insights, organizations may refer to resources on penetration testing methodology and vulnerability management programs to strengthen overall security posture.
Furthermore, organizations should stay informed about the latest threats and vulnerabilities through continuous monitoring and intelligence sharing, ensuring a proactive stance against potential exploitation.
