CVE-2019-25507

Vulnerability

Analysis

Ashop Shopping Cart Software contains an SQL injection vulnerability in the shop parameter of index.php. The application fails to sanitize user input before incorporating it into a SQL query, allowing an attacker to inject arbitrary SQL code. The vulnerability is exploitable via GET requests, the vulnerability is present in the latest version of the software as of March 2019 [1].

Exploitation

An unauthenticated attacker can send a crafted GET request to index.php with a malicious shop value. The provided proof-of-concept demonstrates a UNION-based injection that appends a crafted SQL payload to the original query. The vulnerable parameter is shop, and the attack does not require any authentication or prior knowledge [1].

Impact

Successful exploitation allows an attacker to extract sensitive information from the database, including user credentials, personal data, and other application secrets. The UNION-based technique enables retrieval of arbitrary data from other tables, potentially leading to full database compromise [1].

Mitigation

As of the publication date, no official patch has been released by the vendor. Users are advised to implement input validation and parameterized queries to mitigate the risk. The software may be end-of-life, as the vendor homepage appears inactive [1].
