CVE-2021-3907 is a critical path traversal vulnerability in OctoRPKI, affecting cloudflare debian_linux, cloudflare octorpki, debian debian_linux, and debian octorpki. The flaw allows an attacker to craft a malicious URI containing ".." sequences, enabling arbitrary file writes outside the intended cache directory. This could lead to remote code execution on the host system running OctoRPKI. With a CVSS score of 9.8 (CRITICAL), it presents a severe risk due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. Currently, there is no evidence of active exploitation, no public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage.
