The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:2081-1 advisory.
A double-free was found in the way 389-ds-base handles virtual attributes context in persistent searches.
An attacker could send a series of search requests, forcing the server to behave unexpectedly, and crash.
(CVE-2021-4091)
An access control bypass vulnerability found in 389-ds-base. That mishandling of the filter that would yield incorrect results, but as that has progressed, can be determined that it actually is an access control bypass. This may allow any remote unauthenticated user to issue a filter that allows searching for database items they do not have access to, including but not limited to potentially userPassword hashes and other sensitive data. (CVE-2022-1949)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
