CVE-2011-1826

Vulnerability

An open redirect vulnerability exists in the Administrative Console of CA Arcot WebFort Versatile Authentication Server (VAS) versions prior to 6.2.5. The flaw allows remote attackers to redirect users to arbitrary external websites through unspecified vectors within the console interface. Affected versions include all releases before 6.2.5 [1].

Exploitation

An attacker can exploit this vulnerability by crafting a malicious link that leverages the open redirect in the Administrative Console. No authentication is required, and the attack can be performed remotely. The exact sequence of steps is not publicly detailed, but the vulnerability is triggered by manipulating the redirect mechanism within the console's URL handling [1].

Impact

Successful exploitation enables an attacker to redirect users to arbitrary web sites, facilitating phishing attacks. This can lead to credential theft or other social engineering outcomes, as users may be tricked into visiting malicious pages that appear legitimate [1].

Mitigation

CA Arcot WebFort VAS version 6.2.5 and later contain the fix for this vulnerability. Users should upgrade to version 6.2.5 or newer to mitigate the risk. No workarounds have been disclosed in the available references [1].
