The following CVEs were reported against yubikey-val.
CVE-2020-10184
The verify endpoint in YubiKey Validation Server before 2.40 does not check the length of SQL queries, which allows remote attackers to cause a denial of service, aka SQL injection.
CVE-2020-10185
The sync endpoint in YubiKey Validation Server before 2.40 allows remote attackers to replay an OTP.
For Debian 8 ‘Jessie’, these problems have been fixed in version 2.27-1+deb8u1.
We recommend that you upgrade your yubikey-val packages.
NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
