CVE-2021-25322


A UNIX Symbolic Link (Symlink) Following vulnerability in python-HyperKitty of openSUSE Leap 15.2, Factory allows local attackers to escalate privileges from the user hyperkitty or hyperkitty-admin to root. This issue affects: openSUSE Leap 15.2 python-HyperKitty version 1.3.2-lp152.2.3.1 and prior versions. openSUSE Factory python-HyperKitty versions prior to 1.3.4-5.1.


Security Impact Summary

This vulnerability carries a MEDIUM severity rating with a CVSS v3.1 score of 6.8, requiring local system access to exploit with relatively low complexity without requiring user interaction and does not require pre-existing privileges . The vulnerability impacts confidentiality (data exposure), limited integrity, for affected systems. Impacting 3 products from python-hyperkitty_project, from opensuse, from opensuse organizations running these solutions should prioritize assessment and patching.

Historical Context

Reported in 2021, this vulnerability emerged during an era marked by increased sophistication in supply chain attacks, cloud infrastructure vulnerabilities, and software-as-a-service (SaaS) security challenges. Security practices during this period emphasized zero-trust architectures, container security, and API protection.

How SecUtils Interprets This CVE

SecUtils normalizes and enriches National Vulnerability Database (NVD) records by standardizing vendor and product identifiers, aggregating vulnerability metadata from both NVD and MITRE sources, and providing structured context for security teams. For python-hyperkitty_project's affected products, we extract Common Platform Enumeration (CPE) data, Common Weakness Enumeration (CWE) classifications, CVSS severity metrics, and reference data to enable rapid vulnerability prioritization and asset correlation. This record contains no exploit code, proof-of-concept instructions, or attack methodologies—only defensive intelligence necessary for patch management, risk assessment, and security operations.
