CVE-2022-30003: n/a in n/a
Sourcecodester Online Market Place Site 1.0 is vulnerable to Cross Site Scripting (XSS), allowing attackers to register as a Seller then create new products containing XSS payloads in the 'Product Title' and 'Short Description' fields.
AI Analysis
Technical Summary
CVE-2022-30003 is a medium-severity Cross Site Scripting (XSS) vulnerability affecting Sourcecodester Online Market Place Site version 1.0. The vulnerability allows an attacker who has registered as a Seller on the platform to inject malicious scripts into the 'Product Title' and 'Short Description' fields when creating new product listings. Because these fields are not properly sanitized or encoded, the injected scripts can execute in the browsers of users who view the affected product pages. This type of vulnerability falls under CWE-79, which is a common web application security weakness. The CVSS 3.1 base score of 5.4 reflects that the attack vector is network-based (AV:N), requires low attack complexity (AC:L), but does require privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the vulnerable component. The impact affects confidentiality and integrity to a limited extent (C:L, I:L), but does not impact availability (A:N). Although no known exploits are reported in the wild, the vulnerability could be leveraged to steal session cookies, perform actions on behalf of users, or deliver further malware payloads via the victim's browser. The lack of vendor or product-specific information and absence of patches indicates this may be a niche or less widely deployed application, but the vulnerability is typical of insufficient input validation in web applications.
Potential Impact
For European organizations using Sourcecodester Online Market Place Site 1.0, this vulnerability could lead to unauthorized actions performed in the context of legitimate users, potentially compromising user accounts or exposing sensitive information such as session tokens. This could damage customer trust and lead to regulatory scrutiny under GDPR if personal data is exposed or manipulated. The XSS vulnerability could also be used as a foothold for more complex attacks, including phishing or spreading malware within the user base. Given that the vulnerability requires the attacker to register as a seller, the risk is somewhat mitigated by the need for account creation, but this barrier may be low depending on the platform's registration controls. The impact on European organizations depends on the extent to which this marketplace software is used, particularly by small to medium enterprises or niche online sellers. The vulnerability could also affect third-party integrations or partners relying on this platform, amplifying the risk.
Mitigation Recommendations
To mitigate this vulnerability, organizations should implement strict input validation and output encoding on all user-supplied data, especially in product titles and descriptions. Employing a robust Content Security Policy (CSP) can help reduce the impact of XSS by restricting the execution of unauthorized scripts. User registration processes should include verification steps to prevent automated or malicious account creation. Additionally, monitoring and logging suspicious activities related to product creation can help detect exploitation attempts. If possible, upgrading to a patched or newer version of the software is recommended once available. In the absence of official patches, applying web application firewalls (WAFs) with custom rules to detect and block XSS payloads targeting these fields can provide temporary protection. Educating users to recognize suspicious behavior and ensuring secure session management practices will further reduce risk.
