Improper Link Resolution Before File Access ('Link Following')


Severity High
Score 7.6/10


Windows Internet Naming Service (WINS) allows remote attackers to cause a denial of service (connectivity loss) or steal credentials via a 1Ch registration that causes WINS to change the domain controller to point to a malicious server. NOTE: this problem may be limited when Windows 95/98 clients are used, or if the primary domain controller becomes unavailable.

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.
