Critical Flaws in Versa Concerto Allow Attackers to Escape Docker and Compromise Hosts

May 22, 2025
Vulnerability / Software Security

Cybersecurity researchers have identified several severe vulnerabilities within the Versa Concerto network security and SD-WAN orchestration platform. Exploitation of these flaws could potentially grant attackers control over vulnerable instances. Despite responsible disclosure on February 13, 2025, these issues remain unpatched, leading to a public announcement after the 90-day window expired. According to ProjectDiscovery researchers Harsh Jaiswal, Rahul Maini, and Parth Malhotra, “When combined, these vulnerabilities could enable an attacker to fully compromise both the application and the host system.” The vulnerabilities include:

  • CVE-2025-34025 (CVSS score: 8.6): A privilege escalation and Docker container escape vulnerability resulting from unsafe default mounting of host binary paths, potentially allowing code execution on the host system.

Critical Security Vulnerabilities in Versa Concerto Expose Hosts to Exploitation

Vulnerability / Software Security

Recent investigations by cybersecurity experts have illuminated serious security weaknesses within the Versa Concerto network security and SD-WAN orchestration platform. These critical vulnerabilities could potentially allow malicious actors to gain control over affected instances, presenting significant risks to organizations utilizing this software. Alarmingly, the disclosed vulnerabilities remain unaddressed despite responsible notifications made on February 13, 2025, leading to a public unveiling after the 90-day grace period lapsed.

According to researchers from ProjectDiscovery, including Harsh Jaiswal, Rahul Maini, and Parth Malhotra, the vulnerabilities, when exploited in tandem, could enable an attacker to compromise both the application and the underlying host systems. This illustrates a concerning trend in the software’s security management, as reliance on updates and fixes may not sufficiently protect businesses.

At the heart of these vulnerabilities is CVE-2025-34025, which carries a CVSS score of 8.6. This specific issue involves privilege escalation and Docker container escape, rooted in the insecure default mounting of host binary paths. If successfully exploited, this vulnerability could permit attackers to execute malicious code directly on the host operating system, thereby expanding their control beyond the immediate application environment.

The implications of such a defect are profound, particularly for organizations dependent on the seamless performance of their network security measures. This situation highlights an urgent need for vigilance among business owners about the security of their technologies. Understanding that vulnerabilities exist is crucial, but recognizing the potential for these weaknesses to be leveraged against organizational systems is paramount.

The target of these vulnerabilities encompasses a network of businesses utilizing Versa Concerto, which could range across various sectors, particularly those heavily investing in network management and security solutions. The geographical base of many affected organizations is the United States, where the reliance on advanced digital infrastructure continues to grow.

In the context of the MITRE ATT&CK framework, several adversary tactics and techniques may have been employed in these potential attacks. Initial access could occur through the exploitation of the privilege escalation vulnerability, enabling an adversary to infiltrate systems. Following this, persistence techniques may be utilized to maintain footholds within the network, further endangering sensitive data and systems.

As a result, business leaders are strongly encouraged to assess their usage of the Versa Concerto platform and consider the implications of these vulnerabilities on their cybersecurity posture. Implementing rigorous monitoring and proactive security measures will be essential in mitigating risks associated with this and other emerging threats, ensuring the continued safety of their digital environments amidst evolving cyber challenges.

State-sponsored Russian cyber actors have been linked to a campaign focused on Western logistics and tech firms since 2022. This activity is attributed to APT28 (also known as BlueDelta, Fancy Bear, or Forest Blizzard), connected to the Russian GRU’s 85th Main Special Service Center, Military Unit 26165. Key targets include companies involved in the coordination and delivery of international aid to Ukraine, as highlighted in a joint advisory from agencies across Australia, Canada, Czechia, Denmark, Estonia, France, Germany, the Netherlands, Poland, the United Kingdom, and the United States. The bulletin notes that this cyber-espionage campaign employs a range of previously identified tactics and is likely linked to broader efforts aimed at IP cameras in Ukraine and neighboring NATO countries.

Urgent Vulnerability in Windows Server 2025 dMSA Poses Risk of Active Directory Breach

Cybersecurity / Vulnerability

A critical privilege escalation flaw has been identified in Windows Server 2025, allowing attackers to compromise any user within Active Directory (AD). According to Akamai security researcher Yuval Gordon, the vulnerability exploits the Delegated Managed Service Account (dMSA) feature introduced in Windows Server 2025. This attack can be executed easily with the default configuration, posing a significant threat to organizations relying on AD. “In 91% of the environments we examined, users outside of the domain admin group possessed the necessary permissions to carry out this attack,” Gordon noted in a report shared with The Hacker News. The vulnerability takes advantage of the dMSA feature designed to facilitate migration from legacy service accounts and intended to mitigate Kerberoasting attacks. The attack technique has been dubbed “BadSuccessor” by the researchers.

Vulnerability / Threat Intelligence

A Chinese-speaking threat actor, identified as UAT-6382, has exploited a recently patched remote-code-execution vulnerability in Trimble Cityworks to deploy Cobalt Strike and VShell. According to an analysis by Cisco Talos researchers Asheer Malhotra and Brandon White, “UAT-6382 effectively targeted CVE-2025-0944, conducted reconnaissance, and quickly implemented various web shells and custom malware for sustained access.” Following their infiltration, UAT-6382 showed significant interest in systems related to utility management. Cisco Talos observed these attacks beginning in January 2025, specifically aimed at the enterprise networks of local government entities in the U.S. CVE-2025-0944, with a CVSS score of 8.6, pertains to a vulnerability in the GIS-focused asset management software that could allow for remote code execution. The flaw has been patched.

251 Amazon-Hosted IP Addresses Target ColdFusion, Struts, and Elasticsearch in Exploit Scanning Campaign

Cybersecurity researchers have revealed coordinated cloud-based scanning activities that targeted 75 unique “exposure points” earlier this month. Observed by GreyNoise on May 8, 2025, this activity involved up to 251 malicious IP addresses geolocated in Japan and hosted by Amazon. The threat intelligence firm reported that these IPs exhibited 75 distinct behaviors, including CVE exploits, misconfiguration probes, and reconnaissance activities. Notably, the IPs remained inactive before and after this surge, suggesting they were temporarily rented for a single operation. The scanning efforts targeted various technologies, including Adobe ColdFusion, Apache Struts, Apache Tomcat, Drupal, Elasticsearch, and Oracle WebLogic. This opportunistic operation included attempts to exploit known CVEs and probes for misconfigurations, highlighting the threat actors’ intent to identify weaknesses in web infrastructure.
