Improper Link Resolution Before File Access ('Link Following')
Multiple open redirect vulnerabilities in AIST NetCat 3.12 and earlier allow remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via (1) the redirect parameter in a logoff action to modules/auth/index.php or (2) the url parameter to modules/linkmanager/redirect.php. NOTE: this was reported within an "HTTP Response Splitting" section in the original disclosure.
CWE-59 - Improper Link Resolution Before File Access
'Improper link resolution before file access' occurs when software accesses a file resource but fails to verify that the file isn't a link or shortcut to another file. An attacker can potentially gain access to arbitrary files and from there the impact can vary, depending on the application, from sensitive data exposure to remote code execution.
