CVE-2013-2061 describes a timing attack vulnerability in the openvpn_decrypt function of OpenVPN 2.3.0 and earlier, specifically when operating in UDP mode. This flaw allows remote attackers to potentially extract sensitive information due to a non-constant time HMAC comparison and a padding oracle attack on CBC mode ciphers. With a CVSS score of 2.6 (AV:N/AC:H/Au:N/C:P/I:N/A:N), this vulnerability requires high attack complexity and could lead to partial confidentiality compromise. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
