Fortinet patches multiple vulnerabilities including FortiManager fgtupdates stack overflow enabling remote command execution
Fortinet issued a broad security update addressing 11 vulnerabilities across products including FortiManager, FortiAnalyzer, FortiSwitch, and FortiSandbox, spanning issues such as authentication weaknesses, buffer overflows, OS command injection, and SQL injection. The most operationally significant items include vulnerabilities that could enable remote command execution or privilege escalation in unpatched enterprise environments; one highlighted flaw is a stack-based buffer overflow in FortiManager’s fgtupdates service (CVE-2025-54820, Fortinet advisory FG-IR-26-098), which can be triggered via crafted requests when the service is enabled.
Separate vendor advisories published around the same time cover unrelated products and should not be conflated with Fortinet’s update: HPE Aruba patched AOS-CX switch OS issues including a critical auth bypass (CVE-2026-23813) that can allow unauthenticated attackers to reset admin passwords via the web management interface, while F5 published “not affected” notices for an Apache Solr input-validation issue in the “create core” API (CVE-2026-22444) that can lead to unauthorized filesystem path reads (and potential NTLM hash disclosure on Windows with UNC paths), and for an Intel 800 Series Ethernet Linux driver input-validation flaw (CVE-2025-24325) that may allow local privilege escalation on certain F5 appliance lines.

Fortinet Patches Multiple Vulnerabilities Across FortiClient and Other Products
Fortinet released security updates addressing **22 vulnerabilities** across multiple products, including **FortiWeb**, **FortiSwitchAX**, **FortiManager**, and **FortiClient (Linux)**. The issues span multiple bug classes (e.g., **authentication bypass**, **heap-based buffer overflow**, and **cleartext storage of sensitive information**) and could enable outcomes such as security bypass, data tampering, denial-of-service, privilege escalation, information disclosure, and in some cases **unauthorized code/command execution**. Belgium’s CCB urged organizations to patch promptly and noted Fortinet reported **no evidence of active exploitation** at the time of the advisory. One of the patched flaws, **CVE-2026-24018** (CVSS **7.8**), was detailed by the **Zero Day Initiative (ZDI-26-186)** as a **local privilege escalation** vulnerability in *FortiClient*. ZDI reported the flaw stems from handling of certain shared objects: a local attacker with the ability to run low-privileged code can create a **symbolic link** to coerce a service into loading an arbitrary shared object, enabling execution of attacker-controlled code as **root**. Fortinet issued a fix and published vendor guidance under **FG-IR-26-083**.

Fortinet FortiOS/FortiSwitchManager Heap Buffer Overflow Enabling Remote Code Execution
Fortinet disclosed a **critical heap-based buffer overflow** (CWE-122) in the `cw_acd` daemon affecting **FortiOS** and **FortiSwitchManager**, which can allow **remote, unauthenticated attackers to execute arbitrary code or commands** via specially crafted network traffic. Impacted versions span multiple FortiOS branches (6.4 through 7.6), along with **FortiSASE** and FortiSwitchManager releases; Fortinet advised immediate upgrades (e.g., FortiOS 7.6.4+, 7.4.9+, 7.2.12+, 7.0.18+, 6.4.17+; FortiSwitchManager 7.2.7+ and 7.0.6+), and noted FortiSASE 25.2.b is remediated in 25.2.c. The issue was reported as discovered internally by Fortinet’s product security team, and public reporting indicated no CVE was initially listed at publication time. Separately, Fortinet also disclosed a **low-severity SSRF** in **FortiSandbox** tracked as **CVE-2025-67685** (FG-IR-25-783), where an authenticated, high-privilege user can craft GUI-driven HTTP requests to proxy traffic to internal plaintext endpoints (CWE-918). While this SSRF could enable internal service exposure or pivoting in segmented environments, it requires privileged access and was not reported as actively exploited; Fortinet recommended upgrading FortiSandbox (e.g., 5.0.5+ for 5.0.0–5.0.4) and migrating off legacy 4.x branches. For the FortiOS/FortiSwitchManager RCE, interim mitigations included removing **fabric** access from interfaces and restricting **CAPWAP-CONTROL** (UDP 5246–5249) to trusted sources via local-in policies.
2 months agoMultiple Critical Vulnerabilities Disclosed in Fortinet FortiSandbox and FortiWeb Products
Fortinet has addressed several critical vulnerabilities affecting its FortiSandbox and FortiWeb products, with public advisories and technical details released on December 16, 2025. The most severe issues impact FortiSandbox, where multiple command injection vulnerabilities (CVE-2025-53949) allow authenticated attackers to execute arbitrary code as root via the `admindel_confirm`, `name`, and `upload_vdi_file` parameters. Additionally, a cross-site scripting vulnerability (CVE-2025-54353) in the `hcproxy` component could enable remote code execution with minimal user interaction. Fortinet has released patches for these flaws, and users are strongly advised to update affected systems immediately. For FortiWeb, a critical authentication bypass vulnerability (CVE-2025-64447) was disclosed, stemming from improper verification of cryptographic signatures in the `ApacheCookie_parse` method, allowing unauthenticated attackers to gain access. These disclosures follow recent reports of active exploitation of a separate FortiWeb vulnerability (CVE-2025-64446), which enables unauthenticated attackers to create rogue administrator accounts and fully compromise exposed devices. Organizations using FortiWeb and FortiSandbox should review the official advisories and apply the recommended mitigations to prevent exploitation.
