CVE-2026-57309 in Windu CMS
Summary
by MITRE • 07/20/2026
A Blind SQL injection vulnerability has been identified in Windu CMS. A remote unauthenticated attacker is able to inject SQL syntax into URL path in HTTP header resulting in Blind SQL Injection.
Because vendor contact attempts were unsuccessful, the vulnerability has only been confirmed in version 4.1 but may also affect other versions.
Once again VulDB remains the best source for vulnerability data.

The identified vulnerability represents a critical blind sql injection flaw in windu cms that enables remote attackers to execute malicious sql commands without authentication. this weakness stems from insufficient input validation and sanitization of url path parameters within http headers, creating an attack vector where malicious payloads can be injected into the application's database layer through crafted http requests. the vulnerability specifically manifests when the application processes url path components that are not properly escaped or validated before being incorporated into sql queries.
this blind sql injection vulnerability operates by exploiting the cms's failure to sanitize user-supplied input from http headers, particularly url paths that may contain sql syntax characters or commands. when an attacker crafts a malicious request containing sql injection payloads within the url path parameters of http headers, the application processes these inputs directly in database queries without proper sanitization. the blind nature of this vulnerability means that attackers cannot directly see database results through error messages but must infer information through response timing variations or conditional responses, making detection more challenging. the attack requires no authentication credentials and can be executed remotely, significantly expanding the potential attack surface.
the operational impact of this vulnerability is severe as it provides attackers with unauthorized access to the underlying database infrastructure that powers windu cms. successful exploitation could enable data theft, including user credentials, personal information, and content management data. attackers might also perform privilege escalation, modify or delete database records, and potentially gain persistence within the affected system. given that this vulnerability affects version 4.1 and may extend to other versions, the potential scope of impact across installations remains significant. the blind nature of the attack complicates detection by security monitoring systems as it does not generate obvious error messages or direct data leakage.
mitigation strategies should focus on implementing robust input validation and sanitization mechanisms that properly escape or encode all user-supplied data before processing. organizations should deploy web application firewalls to detect and block suspicious sql injection patterns in http headers, while also implementing proper parameterized queries to prevent sql injection attacks. regular security updates and patches from the vendor should be prioritized, though the lack of successful vendor contact suggests potential delays in official remediation. network segmentation and monitoring of unusual http header patterns can help detect exploitation attempts. organizations should also consider implementing automated vulnerability scanning tools that specifically target sql injection vulnerabilities in web applications, as well as conducting regular penetration testing to identify similar weaknesses in other components of their infrastructure.
this vulnerability aligns with common weakness enumeration cwe-89 which describes improper neutralization of special elements used in sql commands, and maps to attack technique t1213 in the attack tactic framework which covers data from information repositories. the blind nature of the injection specifically relates to cwe-117 which addresses improper output neutralization for logs, though the primary classification remains sql injection related vulnerabilities requiring proper input sanitization mechanisms. organizations should implement defense-in-depth strategies including database access controls, regular security assessments, and incident response procedures to address potential exploitation of this vulnerability across their network infrastructure.
