NewStart CGSL CORE 5.05 / MAIN 5.05 : 389-ds-base Vulnerability (NS-SA-2019-0170)
Medium Nessus Plugin ID 128703
SynopsisThe remote machine is affected by a vulnerability.
DescriptionThe remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has 389-ds-base packages installed that are affected by a vulnerability:
- In 389-ds-base up to version 18.104.22.168, requests are handled by workers threads. Each sockets will be waited by the worker for at most 'ioblocktimeout' seconds.
However this timeout applies only for un-encrypted requests. Connections using SSL/TLS are not taking this timeout into account during reads, and may hang longer.An unauthenticated attacker could repeatedly create hanging LDAP requests to hang all the workers, resulting in a Denial of Service. (CVE-2019-3883)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade the vulnerable CGSL 389-ds-base packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
