Zyxel has released patches to address four security flaws affecting its firewall, AP Controller, and AP products to execute arbitrary operating system commands and steal select information. CVE-2022-26531 - Several input validation flaws in command line interface commands for some versions of firewall, AP controller, and AP devices that could be exploited to cause a system crash.
Zyxel has published a security advisory to warn admins about multiple vulnerabilities affecting a wide range of firewall, AP, and AP controller products. Large organizations use Zyxel products, and any exploitable flaws in them immediately capture the attention of threat actors.
The Cybersecurity and Infrastructure Security Agency has added two more vulnerabilities to its list of actively exploited bugs, a code injection bug in the Spring Cloud Gateway library and a command injection flaw in Zyxel firmware for business firewalls and VPN devices. Threat actors are also abusing a critical Zyxel firmware vulnerability, patched on May 12th and under active exploitation starting the next day, on May 13th. Rapid7 found over 15,000 vulnerable Zyxel products exposed to Internet access, while the Shadowserver Foundation spotted at least 20,000 potentially impacted devices.

The U.S. Cybersecurity and Infrastructure Security Agency on Monday added two security flaws, including the recently disclosed remote code execution bug affecting Zyxel firewalls, to its Known Exploited Vulnerabilities Catalog, citing evidence of active exploitation. Tracked as CVE-2022-30525, the vulnerability is rated 9.8 for severity and relates to a command injection flaw in select versions of the Zyxel firewall that could enable an unauthenticated adversary to execute arbitrary commands on the underlying operating system.
Hackers have started to exploit a recently patched critical vulnerability, tracked as CVE-2022-30525, that affects Zyxel firewall and VPN devices for businesses. It is unclear if these efforts are malicious or just researchers working to map up Zyxel devices currently exposed to adversary attacks.
A critical vulnerability affecting several models of Zyxel firewalls has been publicly revealed, along with a Metasploit module that exploits it.Discovered by Rapid 7 researcher Jake Baines and disclosed to Zyxel on April 13, it was fixed by the company with patches released on April 28, but not publicly acknowledged by the company via an associated CVE or security advisory until now.
Zyxel has moved to address a critical security vulnerability affecting Zyxel firewall devices that enables unauthenticated and remote attackers to gain arbitrary code execution. "A command injection vulnerability in the CGI program of some firewall versions could allow an attacker to modify specific files and then execute some OS commands on a vulnerable device," the company said in an advisory published Thursday.
Zyxel has fixed critical firewall vulnerabilities that could have allowed threat actors to gain full access to devices and the internal corporate networks they are designed to protect. Security researchers at Rapid7 found the flaw, which is now tracked as CVE-2022-30525, and disclosed it to Zyxel on April 13, 2022.
Threat analysts who discovered a vulnerability affecting multiple Zyxel products report that the network equipment company fixed it via a silent update pushed out two weeks ago. More specifically, security researchers at Rapid7 found the flaw, which is now tracked as CVE-2022-30525, and disclosed it to Zyxel on April 13, 2022.
