CVE-2026-76862: Improper Neutralization of Argument Delimiters in a Command ('Argument Injection') in Netcore NR255-V
Netcore NR255-V version 1.5.130703 contains a command argument injection vulnerability in several tcpdump launch routines. This flaw allows attackers with limited privileges to inject crafted arguments into system commands executed by the device. The vulnerability affects specific components related to tcpdump execution and could lead to manipulation of system commands.
AI Analysis
Technical Summary
CVE-2026-76862 is an OS command argument injection vulnerability in Netcore NR255-V version 1.5.130703. The vulnerability exists in the Nettools tcpdump launch paths, including the ntools_start_set_cgi, ntools_tcpdump_start_set_cgi, exe_default, and ntools_proc components. Attackers can inject crafted arguments into these tcpdump launch routines, enabling them to manipulate system commands executed on the device. This vulnerability has a CVSS 4.0 score of 8.7, indicating high severity, with network attack vector, low attack complexity, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
An attacker with low privileges can inject arguments into system commands related to tcpdump execution, potentially leading to unauthorized command execution on the device. This can compromise the confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch link is provided in the available data. Until a patch is available, restrict access to the vulnerable components and monitor for suspicious activity related to tcpdump command execution.
