A flaw was found in pki-core, which could allow a user to get a certificate for another user identity when directory-based authentication is enabled. This flaw allows an authenticated attacker on the adjacent network to impersonate another user within the scope of the domain, but they would not be able to decrypt message content.

It was reported that Certificate System suffers from XSS flaws in the /tus/ and /tus/tus/ URLs, such as:

GET /tus/tus/%22%2b%61%6c%65%72%74%28%34%38%32%36%37%29%2b%22

or

GET /tus/%22%2b%61%6c%65%72%74%28%36%31%34%35%32%29%2b%22

which will in turn output something like:

<!-- var uriBase = "/tus/"+alert(85384)+"; var userid = "admin";

This was reported against Certificate System 8.1 and may also affect Dogtag 9 and 10.

Format string vulnerability in the token processing system (pki-tps) in Red Hat Certificate System (RHCS) 8.1 and possibly Dogtag Certificate System 9 and 10 allows remote authenticated users to cause a denial of service (crash) and possibly execute arbitrary code via format string specifiers in unspecified vectors, related to viewing certificates.

A flaw was found in pki-core. An attacker who has successfully compromised a key could use this flaw to renew the corresponding certificate over and over again, as long as it is not explicitly revoked. The highest threat from this vulnerability is to data confidentiality and integrity.
