Description
This security bulletin contains information about 8 vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2023-1297)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Improper access control (CVE-ID: CVE-2023-2816)
CWE-ID: CWE-284 - Improper Access Control
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:N/SC:N/SI:L/SA:N/E:U/U:Clear
The vulnerability allows a remote user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in Lua extension. A remote user with service:write ACL permissions for an upstream service can modify Envoy proxy config for downstream services without equivalent permissions for those services.
3) Resource exhaustion (CVE-ID: CVE-2023-44487)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:A/U:Amber
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".
Note, the vulnerability is being actively exploited in the wild.
4) Use-after-free (CVE-ID: CVE-2024-23322)
CWE-ID: CWE-416 - Use After Free
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error when idle and request per try timeout occur within the backoff interval. A remote attacker can cause a denial of service condition on the target system.
5) Inefficient CPU Computation (CVE-ID: CVE-2024-23323)
CWE-ID: CWE-1176 - Inefficient CPU Computation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the excessive CPU usage when URI template matcher is configured using regex. A remote attacker can perform a denial of service (DoS) attack.
6) Improper Authentication (CVE-ID: CVE-2024-23324)
CWE-ID: CWE-287 - Improper Authentication
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an authentication bypass when proxy protocol filter sets invalid UTF-8 metadata. A remote attacker can bypass external authentication by downstream connections that use PROXY protocol.
7) Uncaught Exception (CVE-ID: CVE-2024-23325)
CWE-ID: CWE-248 - Uncaught Exception
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to uncaught exception in proxy protocol when using an address type that is not supported by the OS. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
8) NULL pointer dereference (CVE-ID: CVE-2024-23327)
CWE-ID: CWE-476 - NULL Pointer Dereference
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in proxy protocol when command type of LOCAL. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.
