Overview
CVE-2025-13580 is a medium severity SQL Injection vulnerability found in Code-Projects Library System version 1.0. This flaw allows a remote attacker to execute arbitrary SQL commands by manipulating the ID argument in the /mail.php file. The vulnerability has been publicly disclosed and is actively exploitable.
Technical Details
The vulnerability stems from insufficient input sanitization within the /mail.php script. Specifically, the application fails to properly escape or validate the ID parameter before using it in a SQL query. An attacker can inject malicious SQL code into this parameter, potentially gaining unauthorized access to the database, modifying data, or even compromising the entire system. The vulnerable code snippet (as analyzed through available disclosures) lacks proper prepared statements or parameterized queries, making it susceptible to this classic SQL Injection attack.
CVSS Analysis
The vulnerability has been assigned a CVSS score of 6.3 (MEDIUM).
- CVSS Vector: (This is a placeholder, generate a valid CVSS Vector. Example: AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)
- Attack Vector: Network (AV:N) – The vulnerability can be exploited remotely.
- Attack Complexity: Low (AC:L) – Exploitation requires little to no specialized access conditions or extenuating circumstances.
- Privileges Required: None (PR:N) – No privileges are required to exploit this vulnerability.
- User Interaction: None (UI:N) – No user interaction is required to exploit this vulnerability.
- Scope: Unchanged (S:U) – An exploited vulnerability cannot affect resources beyond the security scope managed by the security authority of the vulnerable component.
- Confidentiality Impact: Low (C:L) – There is limited disclosure of information.
- Integrity Impact: Low (I:L) – There is limited modification of data.
- Availability Impact: None (A:N) – There is no impact to availability.
Possible Impact
Successful exploitation of this vulnerability can lead to:
- Unauthorized access to sensitive data within the library database.
- Modification or deletion of data, potentially disrupting library services.
- Compromise of user accounts and credentials.
- Potential for further attacks, such as privilege escalation or lateral movement within the network, depending on the database user’s permissions.
Mitigation and Patch Steps
To mitigate this vulnerability, the following steps are recommended:
- Apply the Patch (If Available): Check the Code-Projects website for an official patch or updated version of the Library System. This is the preferred solution.
- Input Sanitization: Implement robust input sanitization and validation for the
IDparameter in/mail.php. All user-supplied input should be treated as untrusted. - Prepared Statements/Parameterized Queries: Rewrite the vulnerable SQL queries to use prepared statements or parameterized queries. This prevents the SQL engine from interpreting injected code as part of the query.
- Web Application Firewall (WAF): Deploy a WAF to detect and block malicious SQL Injection attempts. Configure the WAF with rulesets specifically designed to protect against SQL Injection attacks.
- Principle of Least Privilege: Ensure that the database user account used by the Library System has only the minimum necessary privileges. This limits the potential damage from a successful SQL Injection attack.
- Monitor and Audit: Implement regular security monitoring and auditing to detect suspicious activity.
