CVE-2023-26033 is a high-severity vulnerability affecting Gentoo Soko, the code that powers packages.gentoo.org. Versions prior to 1.0.1 are susceptible to SQL Injection, which can lead to a Denial of Service (DoS). The vulnerability arises when users select the 'Recently Visited Packages' view on the index page, where the value of the `search_history` cookie is used as a base64 encoded list of atoms. This cookie value is directly loaded into an SQL query, allowing attackers to manipulate it and inject malicious SQL commands.
The implications of this vulnerability are significant, as attackers may exploit the ability to alter the database content. While the database stores only public data, any modification can disrupt service availability. A proof of concept has demonstrated that a malformed cookie can result in database corruption. Fortunately, the vulnerability has been addressed in version 1.0.1, which includes the necessary patches.
Organizations should prioritize patching immediately to mitigate the risk associated with this vulnerability. If immediate upgrades are not feasible, it is recommended to implement workarounds such as using a proxy to drop the `search_history` cookie or sanitizing its value after base64 decoding.
The urgency of addressing this vulnerability is underscored by its high CVSS score of 7.5, indicating a significant threat level to affected systems.
Vulnerability Details
The official description of CVE-2023-26033 notes that it is a SQL Injection vulnerability within Gentoo Soko, impacting versions prior to 1.0.1. The CVSS score associated with this vulnerability is 7.5, classifying it as high severity. The vulnerability enables an attacker to perform unauthorized SQL operations through cookie manipulation.
Publication of this vulnerability occurred on February 25, 2023, and it falls under the Common Weakness Enumeration (CWE-89) category for SQL Injection vulnerabilities. The affected product is Gentoo Soko, with the vendor being Gentoo.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input, specifically the `search_history` cookie. The attack vector is network-based, and the complexity of executing such an attack is low, requiring no privileges or user interaction. The vulnerability primarily impacts data integrity, allowing unauthorized modifications to the database.
The attack's impact includes potential data loss or corruption without affecting confidentiality or availability directly. Given the nature of the vulnerability, organizations must ensure they monitor and remediate any instances of exploitation.
Risk & Impact Analysis
Risk to organizations includes significant disruption of services due to database manipulation, which can compromise operational integrity. The potential blast radius is considerable, as any entity using Gentoo Soko could face downtime or data issues. Organizations should evaluate their exposure based on the CVSS severity score and prioritize remediation efforts accordingly.
