CVE-2017-5361 Explained : Impact and Mitigation

Request Tracker (RT) versions 4.x before 4.0.25, 4.2.x before 4.2.14, and 4.4.x before 4.4.2 are vulnerable to a timing side-channel attack due to the absence of a constant-time comparison algorithm. This allows malicious remote attackers to access sensitive user password information.

Understanding CVE-2017-5361

This CVE entry highlights a security vulnerability in Request Tracker (RT) versions 4.x, 4.2.x, and 4.4.x that could lead to the exposure of user password information.

What is CVE-2017-5361?

CVE-2017-5361 is a vulnerability in RT versions 4.x, 4.2.x, and 4.4.x that arises from the lack of a constant-time comparison algorithm, enabling attackers to exploit a timing side-channel to retrieve sensitive user passwords.

The Impact of CVE-2017-5361

The vulnerability poses a significant risk as it allows remote attackers to extract confidential user password data through a timing side-channel attack, potentially compromising user accounts and system security.
