DescriptionCVE.org

A security vulnerability has been detected in code-projects Accounting System 1.0. This issue affects some unknown processing of the file /viewin_costumer.php of the component Parameter Handler. Such manipulation of the argument cos_id leads to sql injection. The attack can be launched remotely. The exploit has been disclosed publicly and may be used.

AnalysisAI

Remote SQL injection in code-projects Accounting System 1.0 allows unauthenticated attackers to execute arbitrary SQL queries via the cos_id parameter in the /viewin_costumer.php file. The vulnerability has a CVSS score of 6.9 with a public exploit available, enabling attackers to read sensitive data from the database with minimal attack complexity. This is a network-accessible PHP application flaw affecting confidentiality with confirmed public disclosure.

Technical ContextAI

The vulnerability stems from improper input validation in the Parameter Handler component processing the cos_id argument within /viewin_costumer.php, classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The PHP application fails to properly sanitize or parameterize SQL queries, allowing attackers to inject arbitrary SQL syntax through the cos_id parameter. This is a classic SQL injection attack vector in web applications where user input is concatenated directly into SQL statements without escaping or prepared statement usage. The file /viewin_costumer.php likely retrieves customer information and constructs a SQL WHERE clause using the unsanitized cos_id value, permitting an attacker to break out of the intended query structure.

RemediationAI

The primary remediation is to upgrade code-projects Accounting System to a patched version released after the vulnerability disclosure. Immediate mitigation requires implementing parameterized SQL queries (prepared statements) or using an ORM framework to handle all database interactions, specifically modifying /viewin_costumer.php to use bound parameters for the cos_id argument instead of string concatenation. Input validation must be applied to the cos_id parameter, accepting only expected formats (numeric values for customer IDs). Apply Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the cos_id parameter as a temporary containment measure. Security patches and detailed remediation guidance can be referenced through the VulDB submission at https://vuldb.com/vuln/354183 and the disclosed GitHub issue at https://github.com/Xu-Zhihan/CVE/issues/11. Organizations using this application should prioritize patching given the public exploit availability and zero-authentication attack requirement.
