Overview
CVE-2025-55058 is a security vulnerability identified as an Improper Input Validation (CWE-20) flaw. This weakness can allow attackers to potentially manipulate applications or systems by providing malformed or unexpected input. Failing to properly validate user-supplied data can lead to a variety of exploits, including code injection, denial-of-service (DoS), and data corruption. This vulnerability was published on 2025-11-17T18:15:57.543.
Technical Details
The core of this vulnerability lies in the insufficient validation of data received by the affected application. Specifically, the application fails to adequately sanitize or verify the format, type, or range of input before processing it. This lack of validation opens the door for attackers to inject malicious data, such as special characters, excessively long strings, or unexpected data types, which can trigger unintended behavior. Consider a scenario where an application expects an integer but receives a string containing SQL injection commands. Without proper validation, the string could be directly passed to a database query, resulting in unauthorized data access or manipulation.
For example, consider this vulnerable PHP snippet:
<?php
$username = $_GET['username']; // User-supplied input
$query = "SELECT * FROM users WHERE username = '$username'";
// Execute the query without validating $username
?>
An attacker could provide a `username` value like `admin’ OR ‘1’=’1` to bypass authentication or access sensitive data.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigns CVE-2025-55058 a score of 4.5, indicating a MEDIUM severity. While the exploitability is potentially high, the impact is limited, likely affecting confidentiality, integrity, and availability to a lesser degree. The CVSS vector typically reflects factors like the attack vector (e.g., network, local), attack complexity, privileges required, user interaction, scope, confidentiality impact, integrity impact, and availability impact. A detailed CVSS vector will be available from the reference links provided. It’s important to understand the specific CVSS vector components to accurately assess the risk in your environment.
Possible Impact
The impact of CVE-2025-55058 can range from minor inconveniences to significant security breaches, depending on the context and the affected application’s role. Potential consequences include:
- Denial of Service (DoS): Malformed input could crash the application or exhaust resources, preventing legitimate users from accessing the service.
- Data Corruption: Improperly validated data could overwrite or damage stored data, leading to data loss or inconsistency.
- Information Disclosure: Attackers might be able to extract sensitive information by exploiting the vulnerability to bypass security checks.
- Code Injection: In severe cases, attackers could inject and execute arbitrary code on the server, gaining full control of the system.
Mitigation or Patch Steps
To mitigate the risk posed by CVE-2025-55058, the following steps should be taken:
- Apply Patches: Check with the software vendor for available patches or updates. Applying the latest security updates is the most effective way to address the vulnerability.
- Input Validation: Implement robust input validation routines. Validate all data received from external sources, including user input, API calls, and file uploads. Use whitelisting to allow only known good characters or formats.
- Data Sanitization: Sanitize input data to remove or escape potentially malicious characters. Use appropriate encoding functions to prevent code injection attacks.
- Rate Limiting: Implement rate limiting to prevent attackers from flooding the system with malicious requests.
- Web Application Firewall (WAF): Deploy a WAF to filter out malicious traffic and block common attack patterns. Configure the WAF with rules to detect and prevent improper input validation attempts.
- Regular Security Audits: Conduct regular security audits and penetration testing to identify and address vulnerabilities before they can be exploited.
