DescriptionCVE.org

A security flaw has been discovered in code-projects Simple Content Management System 1.0. Affected by this issue is some unknown functionality of the file /web/index.php. Performing a manipulation of the argument ID results in sql injection. Remote exploitation of the attack is possible. The exploit has been released to the public and may be used for attacks.

AnalysisAI

SQL injection in code-projects Simple Content Management System 1.0 allows unauthenticated remote attackers to manipulate the ID parameter in /web/index.php and execute arbitrary SQL queries, potentially leading to unauthorized data access, modification, or deletion. Publicly available exploit code exists and the vulnerability carries a CVSS 6.9 score reflecting moderate confidentiality, integrity, and availability impact across the network-accessible endpoint.

Vulnerability AssessmentAI

Risk Assessment The CVSS 6.9 score with network-accessible attack vector (AV:N), no authentication requirement (PR:N), and no user interaction (UI:N) indicates significant real-world risk. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker sends a crafted HTTP request to /web/index.php with a malicious SQL injection payload embedded in the ID parameter (e.g., ID=1' OR '1'='1), which is directly concatenated into the SQL query without sanitization. The database executes the attacker's injected SQL, allowing the attacker to extract sensitive data, modify records, or potentially execute operating system commands depending on database permissions and configuration. …
Remediation Organizations must immediately upgrade to a patched version of Simple Content Management System if available from code-projects.org, or implement immediate mitigations if no patch has been released. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
