Cybersecurity researchers have uncovered a number of important safety vulnerabilities impacting the Versa Concerto community safety and SD-WAN orchestration platform that might be exploited to take management of vulnerable situations.
It is price noting that the recognized shortcomings stay unpatched regardless of accountable disclosure on February 13, 2025, prompting a public launch of the problems following the top of the 90-day deadline.
“These vulnerabilities, when chained collectively, may enable an attacker to completely compromise each the appliance and the underlying host system,” ProjectDiscovery researchers Harsh Jaiswal, Rahul Maini, and Parth Malhotra mentioned in a report shared with The Hacker Information.
The safety defects are listed beneath –
- CVE-2025-34025 (CVSS rating: 8.6) – A privilege escalation and Docker container escape vulnerability that is brought on by unsafe default mounting of host binary paths and might be exploited to realize code execution on the underlying host machine
- CVE-2025-34026 (CVSS rating: 9.2) – An authentication bypass vulnerability within the Traefik reverse proxy configuration that enables an attacker to entry administrative endpoints, which may then be exploited to entry heap dumps and hint logs by exploiting an inside Spring Boot Actuator endpoint by way of CVE-2024-45410
- CVE-2025-34027 (CVSS rating: 10.0) – An authentication bypass vulnerability within the Traefik reverse proxy configuration that enables an attacker to entry administrative endpoints, which may then be exploited to attain distant code execution by exploiting an endpoint associated to package deal uploads (“/portalapi/v1/package deal/spack/add”) by way of arbitrary file writes
Profitable exploitation of CVE-2025-34027 may enable an attacker to leverage a race situation and write malicious information to disk, finally leading to distant code execution utilizing LD_PRELOAD and a reverse shell.
“Our strategy concerned overwriting ../../../../../../and so on/ld.so.preload with a path pointing to /tmp/hook.so,” the researchers mentioned. “Concurrently, we uploaded /tmp/hook.so, which contained a compiled C binary for a reverse shell. Since our request triggered two file write operations, we leveraged this to make sure that each information have been written inside the similar request.”
“As soon as these information have been efficiently written, any command execution on the system whereas each persevered would outcome within the execution of /tmp/hook.so, thereby giving us a reverse shell.”
Within the absence of an official repair, customers are suggested to dam semicolons in URL paths and drop requests the place the Connection header incorporates the worth X-Actual-Ip. It is also beneficial to observe community visitors and logs for any suspicious exercise.

Versa Networks, in an announcement shared with The Hacker Information, mentioned the problems have been addressed in Concerto model 12.2.1 GA launched on April 16, 2025. The entire response from the corporate is beneath –
Versa is dedicated to sustaining the best requirements of safety and transparency throughout our platform.
On February 13, 2025, three vulnerabilities have been recognized and confirmed in our Concerto software program platform. As a part of our commonplace safety response course of, we developed and validated fixes, which have been accomplished on March 7, 2025, and the hotfix made accessible to prospects. A Typically Accessible (GA) software program launch containing these remediations was made accessible to all prospects on April 16, 2025.
Many shoppers have already upgraded to the April sixteenth launch, although we acknowledge some deployments should be pending. Detailed data on affected releases and mitigation steps has been posted for buyer entry solely.
There isn’t a indication that these vulnerabilities have been exploited within the wild, and no buyer impression has been reported. All affected prospects have been notified by established safety and assist channels with steering on the right way to apply the beneficial updates.
Versa follows accountable disclosure practices and takes a proactive strategy to figuring out, mitigating, and speaking potential dangers. Safety is foundational to our platform, and we proceed to put money into steady monitoring, speedy response, and buyer schooling as a part of our dedication to belief and safety.
(The story was up to date after publication to incorporate a response from Versa Networks concerning the patch data.)
