7.5 highEPSS 0.9%

High (7.5) in nlnetlabs routinator. EPSS 0.9% chance of exploitation in the next 30 days.

NLnet Labs Routinator prior to 0.10.0 produces invalid RTR payload if an RPKI CA uses too large values in the max-length parameter in a ROA. This will lead to RTR clients such as routers to reject the RPKI data set, effectively disabling Route Origin Validation.
