Information disclosure in Phoenix Contact CHARX SEC-3000/3050/3100/3150 EV charging controllers allows an unauthenticated attacker on an adjacent network to download controller log files containing restricted information. No public exploit identified at time of analysis, but the low attack complexity and lack of authentication make opportunistic abuse straightforward once an attacker reaches the same network segment. Reported via CERT@VDE under advisory VDE-2026-060.
A CSRF vulnerability in A CSRF vulnerability in the Link Aggregation configuration interface (CVSS 7.1) that allows an unauthenticated remote attacker. High severity vulnerability requiring prompt remediation.
A cross-site scripting vulnerability (CVSS 7.1) that allows an unauthenticated remote attacker. High severity vulnerability requiring prompt remediation.
Arbitrary command execution with root privileges affects multiple Fl Switch and Fl Nat devices through improper handling of HTTP POST requests in the Root CA certificate transfer workflow. An authenticated high-privileged attacker can exploit this command injection flaw to execute arbitrary commands on the underlying Linux operating system. No patch is currently available for the affected product versions.
SQL injection in Phoenix Contact PLCnext controller web interfaces exposes a notification message SQLite database to manipulation by authenticated low-privilege users. The vulnerable endpoint is network-accessible with no attack requirements beyond a valid low-privilege account, making it trivially exploitable from any networked workstation in OT environments where such accounts exist. Impact is deliberately bounded by design to the notification subsystem - core PLC control logic, I/O, and safety functions are not affected - but notification tampering in industrial contexts may suppress or falsify operational alerts. No public exploit code exists and no CISA KEV listing is present at time of analysis.
Unauthenticated remote denial-of-service in Phoenix Contact's PLCnext Engineer communication interface allows any network-accessible attacker to interrupt engineering access to a broad range of Phoenix Contact industrial controllers. Exploitation triggers CWE-770 resource exhaustion in the PLCnext service, causing it to stop accepting connections from the PLCnext Engineer client application. Recovery requires a manual service restart - an operationally significant constraint in industrial environments where unplanned downtime carries physical and safety implications. No public exploit code is known, and the vulnerability is not listed in CISA KEV at time of analysis.
Remote code execution and denial-of-service in Phoenix Contact PLCnext-family industrial controllers (AXC F 1152/1252/2152/3152, RFC 4072R/S, BPC 9102S/9202S, VPLCnext Control, EPC 15xx and others) arise from a buffer overflow in the PROFINET service that is reachable in the default configuration. An unauthenticated remote attacker on the network can crash/reboot the device or execute arbitrary code, per the vendor CVSS 4.0 rating of 9.3 (critical). This is a CWE-120 classic buffer overflow reported by CERT@VDE; no public exploit identified at time of analysis and it is not on CISA KEV.
A low privileged remote attacker can gain the root password due to improper removal of sensitive information before storage or transfer. Rated high severity (CVSS 8.0), this vulnerability is remotely exploitable, low attack complexity.
A buffer overflow vulnerability (CVSS 5.3). Remediation should follow standard vulnerability management procedures.
A buffer overflow vulnerability (CVSS 6.5). Remediation should follow standard vulnerability management procedures.
Denial of service in Stack Overflow and Fl networking devices results from a stack-based buffer overflow in the file installation workflow that can be triggered by high-privileged attackers through oversized POST parameters. An authenticated attacker with elevated privileges can crash the affected service by exploiting this memory corruption vulnerability. No patch is currently available for the impacted products.
A buffer overflow vulnerability (CVSS 4.9) that allows a high-privileged attacker. Remediation should follow standard vulnerability management procedures.
A buffer overflow vulnerability (CVSS 6.5). Remediation should follow standard vulnerability management procedures.
