A critical zero-day vulnerability (CVE-2024-7029) affecting AVTECH AVM1203 security cameras has been actively exploited for five years [1], posing a high-severity risk to organizations.

Description

The vulnerability allows for code injection and remote code execution through a command injection issue in the brightness function of AVTECH AVM1203 cameras. This flaw has been exploited by a botnet campaign distributing the Corona Mirai malware variant, connecting to hosts via Telnet on ports 23, 2323 [1] [6], and 37215 [1] [5] [6]. Additionally, a botnet named 7777 (or Quad7) has been targeting Microsoft 365 accounts using compromised TP-Link and ASUS routers [3], opening TCP port 7777 on compromised devices [3]. Organizations with impacted AVTECH AVM1203 cameras are advised to upgrade to newer versions as patches are no longer available [1]. The vulnerability affects specific firmware versions of Avtech AVM1203 IP cameras and remains unpatched, posing a significant threat to critical infrastructure sectors.

Conclusion

The Cybersecurity and Infrastructure Security Agency (CISA) has issued an advisory on the AVTECH IP camera zero-day [4], emphasizing the devices’ use in critical infrastructure sectors [4]. The exploit has been used to create a botnet targeting AVM1203 camera devices with specific firmware versions [2]. Researchers recommend replacing all cameras of this type as the vulnerability cannot be patched due to lack of support [5], highlighting the ongoing risks and implications for organizations.
