Microsoft on Monday disclosed that it mitigated a security flaw affecting Azure Synapse and Azure Data Factory that, if successfully exploited, could result in remote code execution. The vulnerability, tracked as CVE-2022-29972, has been codenamed "SynLapse" by researchers from Orca Security, who reported the flaw to Microsoft in January 2022. <!--adsense--> "The vulnerability was specific to

**According to the CVSS metric, the attack vector is local (AV:L). Why does the CVE title indicate that this is a remote code execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the **Attack Vector** is **Local** and **User Interaction** is **Required**, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.

**How could an attacker exploit this vulnerability?** An attacker could exploit the vulnerability by convincing a user to connect a Lightweight Directory Access Protocol (LDAP) client to a malicious LDAP server. When the vulnerability is successfully exploited this could allow the malicious server to gain remote code execution within the LDAP client.

**How could an attacker exploit this vulnerability?** An authenticated attacker could send a specially crafted request to a vulnerable LDAP server. Successful exploitation could result in the attacker's code running in the context of the SYSTEM account.

**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.

**How could an attacker exploit this vulnerability?** This vulnerability could be exploited over the network by an authenticated normal user through a low complexity attack on a server configured as the domain controller.
