CVE-2021-41583 affects vpn-user-portal (eduVPN/Let's Connect!) versions prior to 2.3.14, specifically as packaged for Debian 10, Debian 11, and Fedora. This vulnerability allows remote authenticated users to gain OS filesystem access due to an interaction between QR codes and an 'exec' command using the '-r' option, which can then be used to obtain further VPN access. Rated as Medium severity with a CVSS score of 6.5, the attack vector is network-based with low complexity, requiring low privileges and no user interaction. The primary impact is high confidentiality, as attackers can read sensitive data from the filesystem. Currently, there is no evidence of active exploitation, nor are there any publicly available exploit modules or proof-of-concept code in Metasploit, Nuclei, or ExploitDB. The vulnerability has received minimal community discussion and media coverage.
