CVE-2015-5295

17
FAUCET Score

CVE-2015-5295 describes a denial-of-service vulnerability in the OpenStack Orchestration API (Heat) affecting versions before 2015.1.3 (Kilo) and 5.0.1 (Liberty), as well as products from Fedora, Oracle, and Red Hat. Authenticated remote attackers can exploit this by crafting a template with a malicious resource type, such as file:///dev/zero, leading to memory exhaustion or local file existence disclosure. Rated Medium (CVSS 5.4), this vulnerability has a low attack complexity and requires authenticated access, but can result in denial of service and limited information disclosure. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
