What is CVE-2024-45234?
CVE-2024-45234 is a high-severity denial of service vulnerability in n/a, published on 24 Aug 2024. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
An issue was discovered in Fort before 1.6.3. A malicious RPKI repository that descends from a (trusted) Trust Anchor can serve (via rsync or RRDP) an ROA or a Manifest containing a signedAttrs encoded in non-canonical form. This bypasses Fort's BER decoder, reaching a point in the code that panics when faced with data not encoded in DER. Because Fort is an RPKI Relying Party, a panic can lead to Route Origin Validation unavailability, which can lead to compromised routing.
