CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
CWE-74 The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

Executive Summary

This vulnerability is a SQL injection flaw in SeaCMS version 13.6 or earlier. It exists in the zyapi.php file where the 'ids' parameter is improperly handled. The parameter is inserted into an SQL query without strict validation, allowing attackers to manipulate the query by injecting MySQL expressions. The issue stems from direct concatenation of user input into the SQL query after applying only basic sanitization.

Detection Guidance

To detect this vulnerability, check if your SeaCMS version is up to 13.6. Test the /zyapi.php?ac=videolist endpoint by sending requests with manipulated 'ids' parameters containing SQL expressions like '2+1' or '1 OR 1=1'. Monitor for unexpected database responses or errors indicating SQL injection.

Impact Analysis

An attacker could exploit this to manipulate database queries, potentially accessing or modifying sensitive data. While not a full database compromise, it allows unauthorized data retrieval or alteration. The impact includes data integrity issues, unauthorized access to information, and potential secondary attacks through query manipulation.

Compliance Impact

This vulnerability could lead to unauthorized data access or modification, violating confidentiality requirements in GDPR and HIPAA. It compromises data integrity and may result in non-compliance with security controls requiring protection against SQL injection. Organizations may face regulatory penalties if this flaw leads to data breaches.

Mitigation Strategies

Immediately update SeaCMS to a patched version if available. If not, sanitize the 'ids' parameter by splitting it by commas, validating each item as an integer using intval(), and rejecting non-numeric values. Replace direct SQL concatenation with parameterized queries in seacms/zyapi.php lines 31 and 63.
