What is CVE-2024-23113 Vulnerability?
CVE-2024-23113 is a remote code execution (RCE) vulnerability in Fortinet’s FortiOS, impacting the HTTP/HTTPS interface of certain FortiGate products. A result of a logic flaw in the authentication process, it permits unauthenticated adversaries to execute arbitrary commands without proper credentials. This vulnerability poses significant risks, including data theft, surveillance, and the complete compromise of affected systems.
When was it discovered?
CVE-2024-23113 was publicly disclosed on October 3, 2024. Researchers from WatchTowr Labs identified and responsibly disclosed the vulnerability to Fortinet, which issued advisory patches shortly after its publication.
Affected products & versions
Product | Versions Affected | Fixed Versions / Patch Links |
FortiGate | 7.2.0 – 7.2.3 | |
FortiOS | 7.0.5 – 7.0.12 |
CVE-2024-23113 technical description
The vulnerability derives from improper input validation in the HTTP/HTTPS proxy handling interface. When an attacker sends a specially crafted request, it exploits a logic issue within the session-handling mechanism, bypassing authentication and injecting malicious payloads. The root cause lies in unprotected memory areas, enabling adversaries to control the execution flow of commands on the target device.
Tactics, Techniques & Procedures (TTPs)
Adversaries leveraging CVE-2024-23113 typically scan for exposed FortiGate interfaces on the internet. They use carefully crafted HTTP payloads to exploit the vulnerability, often aiming for lateral movement within compromised network environments.
Indicators of Compromise
Organizations should monitor for anomalous HTTP activity, including requests originating from suspicious IP ranges or users without corresponding session logs. Other indicators include changes in configuration files, unauthorized system reboots, or the presence of unrecognized executables.
Known Proof-of-Concepts & Exploits
Public proof-of-concept (PoC) exploits for CVE-2024-23113 have been released on platforms such as GitHub. Active exploitation campaigns have targeted vulnerable systems across government, healthcare, and financial networks.
How to detect CVE-2024-23113 Vulnerability?
To detect CVE-2024-23113, IT teams should leverage host-based intrusion detection systems (HIDS) and look for deviations in HTTP/HTTPS request patterns. SIEM solutions can be configured with custom rules to identify known exploit signatures. Additionally, thorough reviews of access logs and configuration changes can help discover ongoing attacks.
Impact & risk of CVE-2024-23113 vulnerability
CVE-2024-23113 has a wide-reaching impact on organizations relying on Fortinet’s appliances. A successful exploit results in complete adversary control, threatening business operations, data integrity, and system confidentiality. Industries like finance and critical infrastructure are particularly at risk of espionage or disruption.
Mitigation & remediation strategies
Organizations should immediately apply patches released by Fortinet to eliminate the vulnerability. If patching is not feasible, disabling the administrative interface or restricting access via firewalls until updates can be applied may provide temporary relief. Enforcing strong network segmentation and enabling multi-factor authentication is also advisable.
CVE-2024-23113 Vulnerability FAQs
CVE-2024-23113 is a remote code execution vulnerability in Fortinet’s FortiOS that allows attackers to bypass authentication and execute commands on vulnerable devices. Exploiting a flaw in the HTTP/HTTPS administrative interface, adversaries can fully compromise affected systems.
This vulnerability doesn’t involve traditional “infection.” Attackers exploit exposed FortiGate interfaces by sending malicious HTTP requests, taking control without authentication. Users should protect their systems by patching and limiting interface exposure.
Yes, while many organizations will implement patches, systems that remain unpatched or improperly secured will still be at risk. Active scanning and exploitation may continue to target these vulnerable systems.
Organizations can protect themselves by promptly applying Fortinet’s patches, restricting access to administrative interfaces, regularly monitoring network activity, and implementing robust vulnerability management practices.
