Phoenix Contact FL MGUARD 2102 Environment Variable injection

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as critical, has been found in Phoenix Contact FL MGUARD 2102, FL MGUARD 2105, FL MGUARD 4102 PCI, FL MGUARD 4102 PCIE, FL MGUARD 4302, FL MGUARD 4305, FL MGUARD CENTERPORT VPN-1000, FL MGUARD CORE TX, FL MGUARD CORE TX VPN, FL MGUARD DELTA TX, TX, TX VPN, FL MGUARD GT, GT, GT VPN, FL MGUARD PCI4000, FL MGUARD PCI4000 VPN, FL MGUARD PCIE4000, FL MGUARD PCIE4000 VPN, FL MGUARD RS2000 TX, TX-B, FL MGUARD RS2005 TX VPN, FL MGUARD RS4000 TX, TX-M, TX-P, FL MGUARD RS4004 TX, DTX, DTX VPN, FL MGUARD SMART2, FL MGUARD SMART2 VPN, TC MGUARD RS2000 3G VPN, TC MGUARD RS2000 4G ATT VPN, TC MGUARD RS2000 4G VPN, TC MGUARD RS2000 4G VZW VPN, TC MGUARD RS4000 3G VPN, TC MGUARD RS4000 4G ATT VPN, TC MGUARD RS4000 4G VPN and TC MGUARD RS4000 4G VZW VPN. This issue affects an unknown part of the component Environment Variable Handler. The manipulation of the argument FW_INCOMING.FROM_IP/FW_INCOMING.IN_IP/FW_OUTGOING.FROM_IP/FW_OUTGOING.IN_IP with an unknown input leads to a injection vulnerability. Using CWE to declare the problem leads to CWE-74. The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component. Impacted is availability. The summary by CVE is:

A low privileged remote attacker can perform configuration changes of the firewall services, including packet filter, packet forwarding, network access control or NAT through the FW_INCOMING.FROM_IP FW_INCOMING.IN_IP FW_OUTGOING.FROM_IP FW_OUTGOING.IN_IP environment variable which can lead to a DoS.

The weakness was presented by Andrea Palanca as VDE-2024-039. It is possible to read the advisory at cert.vde.com. The identification of this vulnerability is CVE-2024-43392 since 08/12/2024.
