Stack buffer overflow in WAD

FortiOS explicit proxy WAD daemon stack buffer overflow (CVSS 5.1) allows code execution only with Kerberos and SOCKS configured.

Fortinet advisory FG-IR-26-161 describes a stack-based buffer overflow (CWE-121) in the WAD daemon of FortiOS explicit proxy, scored CVSSv3 5.1. Exploitation requires an attacker able to bypass stack protection and ASLR, and the explicit proxy must be configured with Kerberos authentication and SOCKS enabled. If successful, it yields arbitrary code or command execution in the WAD daemon context via crafted sockets. No exploitation is reported in the advisory.

WireGuard-Linux Stack-Based Buffer Overflow in lsiio (Linux IIO Userspace Tool) Due to Unbounded fscanf

The Linux IIO userspace tool lsiio has a stack buffer overflow in find_type_by_name() caused by unbounded fscanf reads of oversized filesystem-backed attribute values.

A stack-based buffer overflow exists in the Linux Industrial I/O (IIO) userspace utility lsiio. In the find_type_by_name() function, the program reads an unbounded string from a filesystem-backed attribute into a fixed-size stack buffer using fscanf("%s", ...). A crafted or oversized attribute value causes a write beyond the bounds of the destination buffer. Despite the title's reference to WireGuard-Linux, the flaw described is in the IIO lsiio utility.

Palo Alto Networks security advisory (AV26-905)

Canada's Cyber Centre relayed Palo Alto Networks advisories covering PAN-OS, Cloud NGFW, Prisma Access, and Prisma Browser vulnerabilities, including PAN-OS CVE-2026-0310 buffer overflow.

The Canadian Centre for Cyber Security issued advisory AV26-905, noting that as of September 10, 2026, multiple Palo Alto Networks products are affected by vulnerabilities. Affected products include Cloud NGFW on AWS and Azure, multiple PAN-OS versions, Prisma Access, and Prisma Browser prior to 151.26.5.170. The advisory references CVE-2026-0310, a PAN-OS buffer overflow via XML processing (PAN-SA-2026-0012), and the September 2026 Chromium monthly vulnerability update. Administrators are encouraged to review the vendor links and apply available updates.

Cisco RoomOS Stack Overflow Vulnerability

Cisco fixed a stack overflow in the RoomOS USB driver allowing physical-access attackers to execute code with root privileges.

Insufficient boundary checks in the USB driver of Cisco RoomOS allow a buffer overflow when specific data is supplied through the USB port. An unauthenticated local attacker with physical access can connect a malicious USB device and execute arbitrary code with root privileges. Cisco has released software updates and no workarounds address the issue.

Researchers Use Claude to Port Pre-Auth RCE Exploit From One PLC Model to Another

Forescout used Anthropic's Claude to port a working pre-auth RCE exploit for CVE-2021-31886 between WAGO PLCs, executing ARM shellcode on live hardware.

Forescout Vedere Labs used Claude interactively to port an RCE exploit for CVE-2021-31886, a CVSS 9.8 stack buffer overflow in the Nucleus FTP server's USER command, from a WAGO 750-852 to a WAGO 750-831 PLC, running attacker-supplied ARM shellcode. The final RCE stage cost $535.74 in API usage over 8 hours 32 minutes, and a follow-up attempt to build a C2 implant permanently bricked the device. CERT@VDE lists many Nucleus V1-based WAGO models as vulnerable with no updates available; Siemens plans no Nucleus NET remediation. The work follows a joint NSA/CISA/FBI/DOE/EPA advisory warning of AI-generated exploitation scripts targeting internet-exposed Siemens S7 PLCs.
