CallBackery versions before 0.62.0 for Perl allow log injection via newlines in the login name

No exploitation reported by the sources we read.

Am I 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

CallBackery versions before 0.62.0 for Perl allow log injection via newlines in the login name. login() writes the login name to the application log without escaping control characters. The login RPC method needs no authentication, so a name containing a newline followed by text in the log record format adds a forged record. An unauthenticated attacker can forge log records, such as a successful administrator login from an address of their choosing.
