CVE-2025-13277: Critical SQL Injection Vulnerability Threatens Nero Social Networking Site 1.0

Overview

CVE-2025-13277 is a high-severity SQL injection vulnerability discovered in Nero Social Networking Site version 1.0. This flaw allows remote attackers to execute arbitrary SQL commands, potentially leading to data breaches, unauthorized access, and complete compromise of the affected system. The vulnerability resides in the /friendsphoto.php file and is triggered by manipulating the ID argument.

This vulnerability has been published and proof-of-concept exploit code is available, increasing the likelihood of exploitation in the wild. Users of Nero Social Networking Site 1.0 are strongly advised to take immediate action to mitigate this risk.

Technical Details

The vulnerability stems from insufficient input validation and sanitization of the ID parameter within the /friendsphoto.php script. An attacker can inject malicious SQL code through this parameter. For example, a crafted URL like /friendsphoto.php?ID=1' OR '1'='1 could bypass authentication or extract sensitive data from the database.

The absence of proper escaping or parameterized queries enables the attacker to manipulate the SQL query executed by the application. This allows them to read, modify, or delete data, potentially gaining control over the entire database and web application.

CVSS Analysis

• CVSS Score: 7.3 (HIGH)
• This score indicates a significant threat level. The ability to remotely exploit this vulnerability without authentication makes it highly dangerous.

Possible Impact

Successful exploitation of CVE-2025-13277 can have severe consequences, including:

• Data Breach: Sensitive user data, including usernames, passwords, personal information, and potentially financial details, could be exposed.
• Account Takeover: Attackers can gain unauthorized access to user accounts, allowing them to perform malicious activities, impersonate users, and compromise their privacy.
• Database Corruption: Malicious SQL queries could be used to modify or delete data in the database, leading to data loss and application downtime.
• Complete System Compromise: In severe cases, attackers could gain control of the underlying server, allowing them to execute arbitrary code, install malware, and launch further attacks.

Mitigation or Patch Steps

Unfortunately, as Nero Social Networking Site 1.0 is relatively old, official patches may not be available. Therefore, the following mitigation steps are recommended:

1. Discontinue Use: The most effective mitigation is to discontinue the use of Nero Social Networking Site 1.0 and migrate to a more secure platform.
2. Web Application Firewall (WAF): Implement a WAF with SQL injection protection rules to filter malicious requests. Configure the WAF to block requests containing suspicious SQL syntax.
3. Input Validation and Sanitization: If you have access to the source code, implement robust input validation and sanitization for the ID parameter in /friendsphoto.php. Use parameterized queries or prepared statements to prevent SQL injection.
4. Least Privilege Principle: Ensure the database user account used by the application has the minimum necessary privileges. Restrict access to sensitive tables and data.
