CVE-2013-4469

11
FAUCET Score

CVE-2013-4469 describes a denial-of-service vulnerability in OpenStack Compute (Nova) Folsom, Grizzly, and Havana, specifically when the use_cow_images setting is False. This flaw allows a local attacker to consume host file system disk space by transferring a QCOW2 image with a large virtual size but minimal actual data from Glance, due to Nova not verifying the image's true size. The vulnerability has a low severity CVSS score of 1.9 (AV:L/AC:M/Au:N/C:N/I:N/A:P), indicating a local attack vector with medium access complexity and a partial impact on availability. It is a partial fix for a previous vulnerability, CVE-2013-2096. There is no evidence of active exploitation, and no public exploit code is available via Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are minimal, aligning with the majority of reported vulnerabilities.
