Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « affected ».With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.
Description
MMP: All versions prior to v1.0.3, PTP C-series: Device versions prior to v2.8.6.1, and PTMP C-series and A5x: Device versions prior to v2.5.4.1 uses the MD5 algorithm to hash the passwords before storing them but does not salt the hash. As a result, attackers may be able to crack the hashed passwords.
