TRENDnet TEW-812DRU router allows remote authenticated users to execute arbitrary commands via shell metacharacters in the (1) wan network prefix to internet/ipv6.asp; (2) remote port to adm/management.asp; (3) pptp username, (4) pptp password, (5) ip, (6) gateway, (7) l2tp username, or (8) l2tp password to internet/wan.asp; (9) NtpDstStart, (10) NtpDstEnd, or (11) NtpDstOffset to adm/time.asp; or (12) device url to adm/management.asp. NOTE: vectors 9, 10, and 11 can be exploited by unauthenticated remote attackers by leveraging CVE-2013-3098.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

    Weakness class (CWE)

    CWE-78 · Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')

    CVSS vector

    AV:N/AC:M/Au:S/C:C/I:C/A:C

    nvd-primary

    Root cause

    User input is inserted as text into a shell command. The shell may interpret special characters in the input as part of the command.
