Technical details
NSP contains an open redirect vulnerability in URL or redirect parameter handling due to insufficient server-side validation. The vulnerability allows attackers to craft malicious links containing attacker-controlled redirect destinations that are not properly validated before redirection. This is a network-accessible vulnerability requiring user interaction (clicking a malicious link). Attackers can exploit this to redirect users to external phishing sites or malware distribution points, potentially compromising user credentials or enabling social engineering attacks. Patches from Nokia should be consulted for remediation.
