DescriptionCVE.org

A weakness has been identified in code-projects Real State Services 1.0. Impacted is an unknown function of the file /single-list_sale.php?action=add. Executing a manipulation of the argument ID can lead to sql injection. The attack can be executed remotely. The exploit has been made available to the public and could be used for attacks.

AnalysisAI

SQL injection in code-projects Real State Services 1.0 exposes the ID parameter of /single-list_sale.php?action=add to remote, unauthenticated query manipulation, enabling attackers to read or modify database contents. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms no authentication or special conditions are required to reach the endpoint, and the E:P modifier confirms publicly available exploit code referenced via a GitHub CVE disclosure. …

Vulnerability AssessmentAI

Exploitation The CVSS 4.0 vector (PR:N/UI:N/AV:N/AC:L/AT:N) confirms no authentication, no user interaction, and no special attack requirements. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 5.5 (Medium) reflects partial database impact across confidentiality, integrity, and availability (VC:L/VI:L/VA:L), consistent with a SQLi that does not automatically yield OS-level code execution or full database dump without additional chaining. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated remote attacker issues an HTTP GET or POST request to `/single-list_sale.php?action=add&ID=1' OR '1'='1` (or a UNION-based payload), causing the backend PHP code to pass a malformed SQL query to the database. Because no input sanitization or parameterization is in place, the injected SQL alters query logic, potentially returning all rows in a target table or allowing blind extraction of schema and data through boolean- or time-based techniques. …
Remediation No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report.
