CVE-2017-14243
Public exploit available. Not confirmed exploited in the wild yet. No fix published yet.
What to do
No fixed build or workaround is published yet. Limit exposure and watch for a patch.
Steps
Written by AI from the record- Check whether you have a WA3002G4 modem running version WA3002G4-0021.01 and whether its management interface can be reached from untrusted networks.
- Restrict management access to a trusted internal administrator device; disable remote management if it is not needed.
- No fixed version has been published, so contact the modem supplier or internet provider for a supported firmware replacement or device upgrade.
- Change the modem administrator password after restricting access, especially if the interface was exposed.
What it is
From the CVE record
An authentication bypass vulnerability on UTStar WA3002G4 ADSL Broadband Modem WA3002G4-0021.01 devices allows attackers to directly access administrative settings and obtain cleartext credentials from HTML source, as demonstrated by info.cgi, upload.cgi, backupsettings.cgi, pppoe.cgi, resetrouter.cgi, and password.cgi.
In plain language
Written by AI from the recordWA3002G4 modem firmware version WA3002G4-0021.01 can expose administrator passwords to someone on the network, so act if its management pages are reachable.
Unauthenticated network authentication bypass in WA3002G4 modem firmware permits requests to configuration endpoints that disclose administrative settings and plaintext credentials.
If you're affected
- Administrator password exposure
