CVE-2013-0285 is a critical object-injection vulnerability affecting the nori gem for Ruby (versions 2.0.x before 2.0.2, 1.1.x before 1.1.4, and 1.0.x before 1.0.3). This flaw allows remote attackers to execute arbitrary code or cause a denial of service through improper string value casting, leveraging Action Pack's YAML or Symbol type conversion. With a CVSS score of 7.5, it presents a high severity risk due to its network-based attack vector, low attack complexity, and potential for partial confidentiality, integrity, and availability impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this vulnerability.
