CVE-2023-28771 1 Zyxel 38 Atp100, Atp100 Firmware, Atp100w and 35 more 2023-06-09 N/A 9.8 CRITICAL
Improper error message handling in Zyxel ZyWALL/USG series firmware versions 4.60 through 4.73, VPN series firmware versions 4.60 through 5.35, USG FLEX series firmware versions 4.60 through 5.35, and ATP series firmware versions 4.60 through 5.35, which could allow an unauthenticated attacker to execute some OS commands remotely by sending crafted packets to an affected device.
CVE-2023-33010 1 Zyxel 46 Atp100, Atp100 Firmware, Atp100w and 43 more 2023-06-07 N/A 9.8 CRITICAL
A buffer overflow vulnerability in the ID processing function in Zyxel ATP series firmware versions 4.32 through 5.36 Patch 1, USG FLEX series firmware versions 4.50 through 5.36 Patch 1, USG FLEX 50(W) firmware versions 4.25 through 5.36 Patch 1, USG20(W)-VPN firmware versions 4.25 through 5.36 Patch 1, VPN series firmware versions 4.30 through 5.36 Patch 1, ZyWALL/USG series firmware versions 4.25 through 4.73 Patch 1, could allow an unauthenticated attacker to cause denial-of-service (DoS) conditions and even a remote code execution on an affected device.
CVE-2023-22916 1 Zyxel 36 Atp100, Atp100 Firmware, Atp100w and 33 more 2023-05-04 N/A 8.1 HIGH
The configuration parser of Zyxel ATP series firmware versions 5.10 through 5.35, USG FLEX series firmware versions 5.00 through 5.35, USG FLEX 50(W) firmware versions 5.10 through 5.35, USG20(W)-VPN firmware versions 5.10 through 5.35, and VPN series firmware versions 5.00 through 5.35, which fails to properly sanitize user input. A remote unauthenticated attacker could leverage the vulnerability to modify device configuration data, resulting in DoS conditions on an affected device if the attacker could trick an authorized administrator to switch the management mode to the cloud mode.
CVE-2023-22915 1 Zyxel 24 Usg 20w-vpn, Usg 20w-vpn Firmware, Usg Flex 100 and 21 more 2023-05-04 N/A 7.5 HIGH
A buffer overflow vulnerability in the “fbwifi_forward.cgi” CGI program of Zyxel USG FLEX series firmware versions 4.50 through 5.35, USG FLEX 50(W) firmware versions 4.30 through 5.35, USG20(W)-VPN firmware versions 4.30 through 5.35, and VPN series firmware versions 4.30 through 5.35, which could allow a remote unauthenticated attacker to cause DoS conditions by sending a crafted HTTP request if the Facebook WiFi function were enabled on an affected device.
CVE-2023-22914 1 Zyxel 22 Usg Flex 100, Usg Flex 100 Firmware, Usg Flex 100w and 19 more 2023-05-04 N/A 7.2 HIGH
A path traversal vulnerability in the “account_print.cgi” CGI program of Zyxel USG FLEX series firmware versions 4.50 through 5.35, and VPN series firmware versions 4.30 through 5.35, which could allow a remote authenticated attacker with administrator privileges to execute unauthorized OS commands in the “tmp” directory by uploading a crafted file if the hotspot function were enabled.
CVE-2023-22917 1 Zyxel 36 Atp100, Atp100 Firmware, Atp100w and 33 more 2023-05-04 N/A 7.5 HIGH
A buffer overflow vulnerability in the “sdwan_iface_ipc” binary of Zyxel ATP series firmware versions 5.10 through 5.32, USG FLEX series firmware versions 5.00 through 5.32, USG FLEX 50(W) firmware versions 5.10 through 5.32, USG20(W)-VPN firmware versions 5.10 through 5.32, and VPN series firmware versions 5.00 through 5.35, which could allow a remote unauthenticated attacker to cause a core dump with a request error message on a vulnerable device by uploading a crafted configuration file.
CVE-2023-22913 1 Zyxel 22 Usg Flex 100, Usg Flex 100 Firmware, Usg Flex 100w and 19 more 2023-05-04 N/A 8.1 HIGH
A post-authentication command injection vulnerability in the “account_operator.cgi” CGI program of Zyxel USG FLEX series firmware versions 4.50 through 5.35, and VPN series firmware versions 4.30 through 5.35, which could allow a remote authenticated attacker to modify device configuration data, resulting in denial-of-service (DoS) conditions on an affected device.
CVE-2022-38547 1 Zyxel 50 Atp100, Atp100 Firmware, Atp100w and 47 more 2023-02-14 N/A 7.2 HIGH
A post-authentication command injection vulnerability in the CLI command of Zyxel ZyWALL/USG series firmware versions 4.20 through 4.72, VPN series firmware versions 4.30 through 5.32, USG FLEX series firmware versions 4.50 through 5.32, and ATP series firmware versions 4.32 through 5.32, which could allow an authenticated attacker with administrator privileges to execute OS commands.
