Severe Cisco Vulnerability in Unified CM Allows Root Access via Hard-Coded Credentials

July 3, 2025
Vulnerability / Network Security

Cisco has issued patches to fix a critical security flaw in Unified Communications Manager (Unified CM) and Unified CM Session Management Edition (Unified CM SME). This vulnerability could enable an attacker to access susceptible devices with root privileges, achieving a CVSS score of 10.0 under the identifier CVE-2025-20309. In an advisory released on Wednesday, Cisco noted that “this vulnerability arises from the use of static user credentials for the root account, which are meant for development use only.” An attacker could exploit this flaw to log into an affected system and execute arbitrary commands as a root user. Hard-coded credentials often stem from testing or temporary fixes during development, but they should never be present in live environments.

Chinese Hackers Exploit Ivanti CSA Zero-Days to Target French Government and Telecoms

On July 3, 2025, France’s cybersecurity agency disclosed that multiple sectors—including government, telecommunications, media, finance, and transport—were affected by a cyber campaign led by a Chinese hacking group. This group exploited several zero-day vulnerabilities in Ivanti Cloud Services Appliance (CSA) devices. The campaign, identified in early September 2024, has been linked to an intrusion set known as Houken, which reportedly shares characteristics with the threat cluster tracked by Google Mandiant as UNC5174 (also referred to as Uteus or Uetus). According to the French National Agency for the Security of Information Systems (ANSSI), “Houken’s operators use both zero-day vulnerabilities and sophisticated rootkits, alongside a variety of open-source tools primarily developed by Chinese-speaking programmers.” The attack infrastructure utilized by Houken features a mix of components, including commercial VPNs and other tools.

Lazarus Group Leverages Google Chrome Vulnerability to Take Control of Compromised Devices

Oct 24, 2024
Vulnerability / Cyber Attack

The Lazarus Group, a North Korean cyber threat actor, has been linked to the exploitation of a zero-day vulnerability in Google Chrome, allowing them to control infected devices. Cybersecurity firm Kaspersky reported this discovery, which stemmed from a new attack chain identified in May 2024. The attack targeted the personal computer of an unnamed Russian individual using the Manuscrypt backdoor. This involved triggering the zero-day exploit simply by visiting a counterfeit gaming website, “detankzone[.]com,” which aimed at cryptocurrency users. It is believed this campaign began in February 2024. Kaspersky researchers Boris Larin and Vasily Berdnikov noted that the website masqueraded as a professionally designed page for a decentralized finance (DeFi) NFT-based multiplayer online battle arena (MOBA) tank game, enticing users to download a trial version. However, this was merely a façade.
