CVE-2020-11629
The External Command Certificate Validator, which allows administrators to upload external linters to validate certificates, is supposed to save uploaded test certificates to the server.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.58%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An issue was discovered in EJBCA before 6.15.2.6 and 7.x before 7.3.1.2. The External Command Certificate Validator, which allows administrators to upload external linters to validate certificates, is supposed to save uploaded test certificates to the server. An attacker who has gained access to the CA UI could exploit this to upload malicious scripts to the server. (Risks associated with this issue alone are negligible unless a malicious user already has gained access to the CA UI through other means, as a trusted user is already trusted to upload scripts by virtue of having access to the validator.)
