Watchtowr Warns Of Active Exploitation Of Sonicwall Sma 100 Devices

watchTowr reveals progressive exploitation of SonicWall SMA 100 vulnerabilities (CVE-2024-38475 & CVE-2023-44221) perchance starring to afloat strategy takeover and convention hijacking. Learn astir affected models, disposable patches, and CISA’s urgent warning.

Cybersecurity researchers astatine watchTowr person spotted malicious threat actors actively leveraging known information vulnerabilities successful SonicWall’s wide utilized SMA 100 (Secure Mobile Access) appliances.

This discovery, documented successful their latest blog station shared pinch Hackread.com, reveals really attackers are combining 2 circumstantial vulnerabilities to perchance summation complete administrative power complete these devices.

Evidence suggests these techniques are already being employed successful real-world attacks, making contiguous consciousness and action captious for affected businesses. The investigation started aft clients reported different activity connected nan SonicWall system, starring to nan find of a vulnerability successful nan Apache web server package tracked arsenic CVE-2024-38475, discovered by Orange Tsai. The flaw allows unauthorized record reading, and its beingness successful nan SonicWall configuration makes nan appliance vulnerable.

The 2nd captious vulnerability, CVE-2023-44221, is simply a bid injection flaw discovered by Wenjie Zhong (H4lo) of DBappSecurity Co., Ltd. This weakness allows an attacker who has already gained immoderate level of entree to execute their ain commands connected nan affected system.

The operation of these 2 vulnerabilities is peculiarly concerning. The record publication vulnerability (CVE-2024-38475) tin beryllium utilized to extract delicate information, specified arsenic administrator convention tokens, efficaciously bypassing nan request for login credentials. Once this first foothold is established, nan bid injection vulnerability (CVE-2023-44221) tin beryllium exploited to execute arbitrary commands, perchance starring to convention hijacking and afloat strategy compromise.

The vulnerabilities impact nan SMA 100 bid appliances, including models SMA 200, SMA 210, SMA 400, SMA 410, and SMA 500v. The blog station reveals nan method steps involved, including exploiting nan Apache “Filename Confusion” and “DocumentRoot Confusion,” and accessing delicate files for illustration nan convention database.

Researchers moreover demonstrated really to flooded challenges successful reliably extracting this information by utilizing techniques for illustration requesting nan record successful chunks to utilization nan bid injection flaw, and moreover bypass first attempts astatine information measures implemented successful nan SonicWall software.

In their report, watchTowr researchers statement that these vulnerabilities could beryllium chained together to execute a complete strategy takeover. Reportedly, CVE-2023-44221 was patched successful December 2023 (firmware type 10.2.1.10-62sv and higher), and CVE-2024-38475 was patched successful December 2024 (firmware type 10.2.1.14-75sv and higher).

WatchTowr has besides developed a instrumentality (Detection Artefact Generator) to observe and utilization vulnerabilities. This instrumentality tin thief organizations measure their risk, instrumentality basal patches, and unafraid measures

The truth that CISA added these vulnerabilities to its Known Exploited Vulnerabilities (KEV) catalogue connected May 1, 2025, and mandated national agencies to use nan patches by May 22, 2025, highlights nan urgency of nan situation. That’s why it is important to promptly reside them successful captious separator devices for illustration nan SonicWall SMA100.
