Issue
LSWS users may see errors like
2022-10-08 15:51:43.110779 ERROR [ModSecurity] failed to parse a modsec variable. while parsing: %{REQUEST_COOKIES.pwg_id} 2022-10-08 15:51:43.110937 ERROR [ModSecurity] failed to parse a modsec variable. while parsing: %{REQUEST_COOKIES.pwg_id}
in the logs.
Environment
- Imunify360
- LSWS
- ModSecurity
Solution
It is safe to disregard those errors in accordance with the LSWS documentation:
The above error messages simply mean the given variables are not supported by LSWS yet. The errors can simply be ignored. We periodically review our mod_security engine and frequently add new support. Stay tuned.
Cause
Not all variables are supported by LSWS, unlike Apache.
