Vulnerability Details
The vulnerability description states that follow-redirects is vulnerable to exposure of private personal information to an unauthorized actor. The CWE classification for this vulnerability is CWE-359, indicating improper validation of input data. The vulnerability was published on January 10, 2022, and has been modified since its initial disclosure.
The CVSS version 3.1 vector string for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N, with a base score of 6.5. This signifies a medium severity level due to high confidentiality impact, with no integrity or availability impact.
Affected products include follow-redirects and Siemens Sinec Ins, particularly versions prior to the patch. The vulnerability's configurations indicate susceptibility in various versions of these products.
Technical Analysis
The root cause of the vulnerability resides in the improper handling of redirect requests, which can lead to the exposure of sensitive user information. Attackers may exploit this vulnerability by crafting malicious requests that manipulate the redirect functionality of the affected applications.
The attack vector is network-based, requiring low complexity and no authentication. This means that attackers can exploit the vulnerability remotely without needing access to the system. User interaction is necessary, as users must engage with the affected service or application to trigger the vulnerability.
The confidentiality impact is rated high, indicating that sensitive information may be exposed to unauthorized parties. However, there is no impact on integrity or availability, meaning the primary concern is the leakage of private data.
Risk & Impact Analysis
Risk to organizations includes potential exposure of private personal information, leading to privacy violations and regulatory ramifications. The blast radius for this vulnerability can be significant, especially in environments where sensitive user data is handled.
Given the CVSS score of 6.5, organizations should address this vulnerability in their priority patch cycle. With the potential for high confidentiality impact, timely remediation is critical to ensure the protection of user data.
