CVE-2024-28102
Description
An uncontrolled resource consumption vulnerability was found in python-jwcrypto. If a malicious JWE token with a high compression ratio is passed to the server, the server will consume a lot of memory and processing time, leading to a denial of service.
Statement
The CVE-2024-28102 vulnerability in JWCrypto represents a moderate severity issue due to its potential impact on system availability and resource consumption. While the vulnerability allows for a denial of service (DoS) attack, it requires an attacker to craft a malicious JWE Token with a high compression ratio. This specific condition limits the practical exploitability of the vulnerability to some extent, as it demands a more sophisticated attack approach than common vulnerabilities. Nonetheless, if exploited, the vulnerability can lead to significant memory exhaustion and increased server processing time, impacting the overall performance and availability of the affected system.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
