Palo Alto PAN-OS Buffer Overflow Lets Attackers Execute Arbitrary Code as Root
Palo Alto Networks fixed CVE-2026-0310, a CVSS 9.2 unauthenticated PAN-OS buffer overflow enabling root code execution on PA-Series firewalls.
Palo Alto Networks published an advisory on September 9, 2026 for CVE-2026-0310, a CWE-787 out-of-bounds write in PAN-OS XML processing with a CVSS v4.0 base score of 9.2, affecting the management and dataplane interfaces. Unauthenticated attackers could execute arbitrary code as root on PA-Series hardware firewalls, while VM-Series faces denial-of-service impact and Prisma Access and Cloud NGFW have reduced, authenticated exposure. Affected releases include PAN-OS 10.2, 11.1, 11.2, 12.1, and 12.2 before fixed maintenance releases such as 12.2.3, 12.1.4-h10, 11.2.13-h2, 11.1.16-h2, and 10.2.18-h10; no workaround is available. Palo Alto is not aware of malicious exploitation but classifies remediation urgency as highest.

Microsoft's September 2026 Patch Tuesday addresses a record 966 vulnerabilities, including 105 rated Critical, 81 of them remote code execution bugs. Two zero-days were actively exploited: a Windows Update Stack link-following flaw and a Windows ALPC heap-based buffer overflow, both allowing local elevation to SYSTEM privileges. The ALPC flaw was reported by Volexity and Proofpoint researchers, while the Update Stack flaw was credited to Romain Deperne and the Microsoft Threat Intelligence Centre. Microsoft shared no details on how the flaws were exploited in attacks.

Philippine Nuclear and Naval Targets Hit by Suspected Chinese Operator
Suspected Chinese-speaking operator breached Philippine nuclear research and naval supplier systems via ownCloud CVE-2023-49103 and WordPress CVE-2024-28000.
Hunt.io found an exposed staging server containing custom Python scripts, logs, and stolen data documenting intrusions against a Philippine nuclear research body and a marine engineering company serving the Philippine Navy. The actor exploited an ownCloud authentication bypass (CVE-2023-49103) using empty-secret pre-signed WebDAV URLs and a LiteSpeed Cache plugin flaw (CVE-2024-28000) to gain WordPress admin access, also guessing passwords against XML-RPC with rockyou.txt. Roughly 9 GB was referenced as stolen from the nuclear agency, including reactor databases, radiation-safety records, and staff passport data; Simplified Chinese labels suggest a Chinese-speaking operator.

Threat Brief: OWASSRF Vulnerability Exploitation
Unit 42 details active exploitation of Exchange SSRF flaws CVE-2022-41080/CVE-2022-41082 via the OWASSRF method, deploying the SilverArrow PowerShell backdoor.
Unit 42 documents OWASSRF, an exploit chain combining CVE-2022-41080 and CVE-2022-41082 to achieve remote code execution on Microsoft Exchange via Outlook Web Access, bypassing Microsoft's ProxyNotShell mitigations. Active exploitation was observed in late November and early December 2022, affecting at least eight organizations. Attackers authenticated to Exchange, then executed a PowerShell backdoor tracked as SilverArrow to create admin accounts, install AnyDesk, tunnel RDP via PuTTY Link, and dump LSASS memory for credential theft. Exploitation is isolated rather than mass-scale because authentication is required.
