CVE-2023-2454 is a high-severity vulnerability affecting PostgreSQL, identified on June 9, 2023. This vulnerability allows an authenticated attacker with elevated database-level privileges to execute arbitrary code, which poses a significant risk to organizations using affected PostgreSQL versions. With a CVSS score of 7.2, this vulnerability is classified as high severity and requires immediate attention.
Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability. The ability for an attacker to execute arbitrary code can lead to severe consequences, including data breaches and system compromise. This vulnerability has been designated as having a high exploitability potential, making it critical for organizations to take action.
The urgency for defenders to address this vulnerability is underscored by its potential for exploitation. As the vector for attack is over the network with low complexity and high privileges required, it is essential to ensure that only authorized users have access to sensitive database operations.
In summary, CVE-2023-2454 poses a significant risk due to its potential for code execution by authenticated users with elevated privileges. Organizations should act swiftly to remediate this vulnerability to safeguard their systems and data.
Vulnerability Details
This vulnerability allows schema_element to defeat protective search_path changes. It was discovered that certain database calls in PostgreSQL could permit an authenticated attacker with elevated database-level privileges to execute arbitrary code. The vulnerability is categorized under CWE-20, indicating improper input validation.
The CVSS score of 7.2 categorizes this vulnerability as high severity, indicating a substantial impact on confidentiality, integrity, and availability. The affected versions include PostgreSQL 11.0 through 11.20, 12.0 through 12.15, 13.0 through 13.11, 14.0 through 14.8, and 15.0 through 15.3. The vulnerability was officially published on June 9, 2023.
Technical Analysis
The root cause of CVE-2023-2454 is linked to improper handling of database schema elements, allowing for unauthorized execution of code by users with elevated privileges. The attack vector is network-based, requiring low complexity for execution. While high privileges are necessary for exploitation, user interaction is not required, making it easier for attackers to leverage this vulnerability.
The impact on confidentiality, integrity, and availability is significant, as attackers can potentially manipulate data and disrupt services. Organizations must monitor their PostgreSQL deployments closely and ensure that adequate security measures are in place to mitigate these risks.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access to sensitive data, leading to data breaches and operational disruptions. The blast radius of this vulnerability could extend to any organization utilizing affected versions of PostgreSQL, particularly those with elevated privileges granted to users.
The urgency assessment is high, given the CVSS score of 7.2 and the potential for exploitation without user interaction. Organizations should implement immediate patching and review their access control policies to limit exposure to this vulnerability.
