CVE-2023-26443
CWE-89Published: August 2, 2023· Updated: Jun 17, 2026
Official Description
Full-text autocomplete search allows user-provided SQL syntax to be injected to SQL statements. With existing sanitization in place, this can be abused to trigger benign SQL Exceptions but could potentially be escalated to a malicious SQL injection vulnerability. We now properly encode single quotes for SQL FULLTEXT queries. No publicly available exploits are known.
Risk Analysis
The Open-Xchange AppSuite backend contains a flaw in its full-text autocomplete search that allows for SQL injection. While currently limited to triggering exceptions, it could be escalated to malicious SQL injection, warranting a critical severity rating.
No public exploits are known, and the vulnerability is not in CISA KEV. It is remotely exploitable with low attack complexity.
Ensure the application is updated to a version that includes the fix, which involves proper encoding of single quotes for SQL FULLTEXT queries.
Technical Analysis
CVE-2023-26443 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-89): SQL injection vulnerabilities allow attackers to manipulate database queries, potentially exposing or modifying sensitive data.
