CVE-2012-5055

19
FAUCET Score

CVE-2012-5055 affects VMware SpringSource Spring Security versions before 2.0.8, 3.0.8, and 3.1.3. The vulnerability in DaoAuthenticationProvider allows remote attackers to enumerate valid usernames due to a shorter response delay when an invalid username is provided, as the system does not attempt password validation in such cases. This issue has a CVSS score of 5.0, indicating a medium severity with low attack complexity and potential for information disclosure (username enumeration). There is no evidence of active exploitation, no known public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage, suggesting it is not a widely targeted vulnerability.
