CVE-2024-36048 is a critical vulnerability identified in the Qt Network Authorization framework. This vulnerability allows attackers to leverage guessable values due to the use of the time to seed the pseudo-random number generator (PRNG). The affected versions include Qt prior to 5.15.17, 6.x prior to 6.2.13, 6.3.x through 6.5.x prior to 6.5.6, and 6.6.x through 6.7.x prior to 6.7.1.
With a CVSS score of 9.8, this vulnerability is classified as critical, indicating significant risk to organizations. The attack vector is network-based with low complexity, requiring no privileges or user interaction. Risk to organizations includes exposure of sensitive data and potential system compromise.
Given the critical nature of this vulnerability, organizations should prioritize patching immediately. The publication date for this CVE is May 18, 2024, and it is vital for security teams to implement the necessary updates to protect against potential exploitation.
The vulnerability has been marked as modified, highlighting ongoing concerns regarding its impact. Security practitioners must remain vigilant and monitor their systems closely.
This vulnerability underscores the importance of robust security practices in software development, particularly concerning cryptographic implementations.
Vulnerability Details
The vulnerability description states that QAbstractOAuth in Qt Network Authorization uses only the time to seed the PRNG. This implementation flaw may lead to guessable values, compromising the security of applications utilizing this library.
The CVSS version 3.1 vector string indicates a base score of 9.8, categorized as critical, with high impacts on confidentiality, integrity, and availability.
The affected products include various versions of the Qt framework and Fedora operating systems, specifically versions 39 and 40.
Technical Analysis
The root cause of this vulnerability lies in the reliance on the time to seed the PRNG. An attacker could exploit this weakness to predict the output of the PRNG, leading to potential unauthorized access or data exposure.
The attack vector is network-based (AV:N), and the attack complexity is low (AC:L), meaning that no special conditions need to be met for an attack to succeed. Additionally, no privileges are required (PR:N), and there is no need for user interaction (UI:N), which increases the vulnerability's exploitability.
The impacts on confidentiality, integrity, and availability are all rated as high (C:H, I:H, A:H), emphasizing the critical nature of this vulnerability for affected organizations.
Risk & Impact Analysis
Real-world deployment of this vulnerability in critical systems poses significant risks, especially in applications that rely on robust security for authorization and data protection. Organizations utilizing the affected Qt versions or Fedora systems must understand the potential for widespread impact.
The potential blast radius of this vulnerability is extensive, as it can affect any application built on the compromised versions of Qt. The urgency for organizations to address this vulnerability is high, given the critical severity score and the potential for exploitation.
Organizations should prioritize patching immediately to prevent unauthorized access and data breaches. The CVSS score, in conjunction with the KEV status indicating that this vulnerability is not in the KEV catalog, should prompt a proactive response.
