Vulnerability from variot
Out-of-bounds Read vulnerability in iscsi_snapshot_comm_core in Synology DiskStation Manager (DSM) before 6.2.3-25426-3 allows remote attackers to execute arbitrary code via crafted web requests. Synology DiskStation Manager (DSM) Is vulnerable to an out-of-bounds read.Information is obtained, information is tampered with, and service is disrupted (DoS) It may be put into a state. This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of Synology DS418play. Authentication is not required to exploit this vulnerability.The specific flaw exists within the processing of the HandleSendMsg parameter sent to StartEngCommPipeServer. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated structure. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Synology DiskStation Manager (DSM) is an operating system for network storage servers (NAS) developed by Synology, Taiwan. The operating system can manage data, documents, photos, music and other information
