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) a signed object containing an empty signedAttributes field. Fort accesses the set's elements without sanitizing it first. Because Fort is an RPKI Relying Party, a crash can lead to Route Origin Validation unavailability, which can lead to compromised routing.

Title: FORT Validator vulnerabilities
Summary: Several security issues were fixed in FORT Validator.
Niklas Vogel and Haya Schulmann discovered that FORT Validator did not
perform proper input validation when parsing certain RPKI repository data.
A remote attacker could possibly use this issue to cause FORT Validator to
crash, resulting in a denial of service. (CVE-2024-45234, CVE-2024-45235,

Niklas Vogel and Haya Schulmann discovered that FORT Validator did not
perform proper input validation when parsing resource certificates. A
remote attacker could possibly use this issue to cause a denial of service
or execute arbitrary code. (CVE-2024-45237)

CVE-2024-45236 [HIGH] CWE-20 GHSA-v5cx-w2w4-m488: An issue was discovered in Fort before 1
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) a signed object containing an empty signedAttributes field. Fort accesses the set's elements without sanitizing it first. Because Fort is an RPKI Relying Party, a crash can lead to Route Origin Validation unavailability, which can lead to compromised routing.
