Detailsinfo

A vulnerability was 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. It has been classified as critical. Affected is an unknown code block of the component Environment Variable Handler. The manipulation of the argument OSPF_INTERFACE.SIMPLE_KEY/OSPF_INTERFACE.DIGEST_KEY with an unknown input leads to a injection vulnerability. CWE is classifying the issue as 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. This is going to have an impact on availability. CVE summarizes:

A low privileged remote attacker can perform configuration changes of the ospf service through OSPF_INTERFACE.SIMPLE_KEY, OSPF_INTERFACE.DIGEST_KEY environment variables which can lead to a DoS.

The weakness was presented by Andrea Palanca as VDE-2024-039. The advisory is available at cert.vde.com. This vulnerability is traded as CVE-2024-43389 since 08/12/2024. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1055 by the MITRE ATT&CK project.

Upgrading eliminates this vulnerability.
