DescriptionCVE.org

A vulnerability was identified in CodeAstro Apartment Visitor Management System 1.0. Affected by this vulnerability is an unknown functionality of the file password-recovery.php. The manipulation of the argument email leads to sql injection. Remote exploitation of the attack is possible. The exploit is publicly available and might be used.

AnalysisAI

SQL injection in CodeAstro Apartment Visitor Management System 1.0 allows remote unauthenticated attackers to manipulate backend database queries through the email parameter of the password-recovery.php script. The CVSS 4.0 vector (AV:N/AC:L/PR:N/UI:N) confirms no authentication or special configuration is required, and a public proof-of-concept exploit is available on GitHub, lowering the skill threshold for opportunistic attacks. …

Vulnerability AssessmentAI

Exploitation No special conditions are required - exploitation is possible by any remote, unauthenticated actor who can send an HTTP request to the password-recovery.php endpoint of a publicly accessible CodeAstro Apartment Visitor Management System 1.0 instance. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 6.9 with network attack vector, no authentication, and no complexity requirement reflects a meaningful but bounded risk - the Low ratings across VC/VI/VA indicate partial rather than full database compromise without additional exploit chaining. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated attacker sends a crafted HTTP POST request to password-recovery.php with a malicious SQL payload in the email field - for example, a UNION-based injection to retrieve user credentials or a blind boolean payload to enumerate database contents. A public proof-of-concept demonstrating this technique is available at https://github.com/Witiers/CVEs/issues/2, making this reproducible with minimal skill. …
Remediation No vendor-released patch has been identified at time of analysis - no patched version appears in available intelligence, and the vendor site (https://codeastro.com/) does not surface a security advisory. … Detailed patch versions, workarounds, and compensating controls in full report.
