Two memory safety vulnerabilities in WatchGuard and Panda Security products could lead to code execution with System privileges.

Vulnerabilities in WatchGuard and Panda Security products could allow attackers to cause denial of service (DoS) conditions or execute arbitrary code with System privileges.
The bugs were identified in the Panda Kernel Memory Access driver (pskmad_64.sys) that is installed alongside WatchGuard EPDR, Panda AD360, and Panda Dome for Windows.
The first of the issues, tracked as CVE-2023-6330, is described as a memory pool overflow defect that could allow an attacker to overflow the allocated kernel memory pool.
According to cybersecurity firm Sophos, which identified the vulnerabilities, the driver fails to properly validate the contents of registry values related to OS version, allowing an attacker to place maliciously crafted content in these registries and overflow the memory.
“The minimum impact is a denial of service. With additional research, an attacker might be able to achieve RCE by chaining CVE-2023-6330 with other vulnerabilities,” Sophos explains.
The second security defect, CVE-2023-6331, is an out-of-bounds write issue also leading to a kernel memory overflow.
According to Sophos, an attacker could exploit the vulnerability by sending a maliciously crafted packet via an IRP request that has a specific IOCTL code, potentially overflowing a non-paged memory area.
“The vulnerability exists due to missing bounds check when moving data via memmove to a non-paged memory pool,” Sophos notes.
While both CVE-2023-6330 and CVE-2023-6331 could lead to code execution, their impact is mitigated by the fact that an attacker needs to be authenticated with administrative privileges to successfully exploit them.
Both security holes were addressed with the release of WatchGuard EPDR and Panda AD360 version 8.00.22.0023, and Panda Dome version 22.02.01.
The updates also resolve an arbitrary kernel memory read flaw in the pskmad_64.sys driver, which could allow an attacker to read arbitrary kernel memory.
