FAQ / Articles
FAQ
Are there any special conditions necessary for this vulnerability to be exploitable? Yes. This vulnerability is only exploitable if the MaxReceiveBuffer LDAP policy is set to a value higher than the default value. Systems with the default value of this policy would not be vulnerable. For more information, please see LDAP policies.
FAQ
According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability? Successful exploitation of this vulnerability requires an attacker to prepare the target environment to improve exploit reliability.
FAQ
According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution? An authenticated victim who is connected to the network must be tricked or persuaded to connect to a malicious LDAP server using their LDAP client application. After the connection is made, the server can send specially crafted replies to the client that exploit the vulnerability and permit execution of arbitrary code within the context of the user's LDAP client application.
