A vulnerability was found in SQLite SQLite3 up to 3.43.0 and classified as critical. This issue affects the function sessionReadRecord of the file ext/session/sqlite3session.c of the component make alltest Handler. The manipulation leads to heap-based buffer overflow. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-248999.
The severity level is classified as medium with a CVSS score of 5.5. This indicates that the vulnerability poses a moderate risk to organizations, particularly those utilizing SQLite in their applications.
Risk to organizations includes potential unauthorized access and system instability due to the heap-based buffer overflow. The vulnerability can be exploited through adjacent network access, making it crucial for affected entities to take swift action.
Given the nature of this vulnerability and its critical classification, organizations should prioritize patching immediately. Regular updates and timely application of patches are essential in maintaining the security integrity of systems.
Vulnerability Details
The vulnerability affects SQLite SQLite3 up to version 3.43.0, specifically targeting the sessionReadRecord function within the sqlite3session.c file. The CWE classifications associated with this vulnerability include CWE-122 and CWE-119, indicating issues related to improper restriction of operations within the bounds of a memory buffer.
The publication date of this vulnerability is December 29, 2023, and it has been classified as modified since its initial disclosure.
Technical Analysis
The root cause of this vulnerability is a heap-based buffer overflow that can occur if the sessionReadRecord function processes input that exceeds the allocated buffer size. This vulnerability can be exploited by an attacker with adjacent network access, requiring low complexity and low privileges, as user interaction is not necessary.
The attack vector is classified as adjacent network, meaning that an attacker must be on the same local network as the target system. The attack complexity is low, and it requires low privileges to execute. The confidentiality, integrity, and availability impacts are all rated as low, indicating that while the risks are present, they do not result in severe compromises.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is significant, especially for organizations using SQLite in sensitive applications. The potential for exploitation could lead to unauthorized access to data or system disruptions.
Organizations should assess their deployment of SQLite and consider the impact this vulnerability may have on their operations. The urgency to address this vulnerability is high due to its medium CVSS score, which suggests that timely remediation should be prioritized.
