The U.S. Nationwide Security Agency (NSA) on Tuesday stated a menace actor tracked as APT5 has been actively exploiting a zero-day flaw in Citrix Software Shipping and delivery Controller (ADC) and Gateway to acquire over influenced methods.
The critical remote code execution vulnerability, discovered as CVE-2022-27518, could make it possible for an unauthenticated attacker to execute commands remotely on vulnerable units and seize management.
Productive exploitation, having said that, demands that the Citrix ADC or Citrix Gateway appliance is configured as a SAML provider supplier (SP) or a SAML id service provider (IdP).

The pursuing supported variations of Citrix ADC and Citrix Gateway are influenced by the vulnerability –
- Citrix ADC and Citrix Gateway 13. ahead of 13.-58.32
- Citrix ADC and Citrix Gateway 12.1 in advance of 12.1-65.25
- Citrix ADC 12.1-FIPS before 12.1-55.291
- Citrix ADC 12.1-NDcPP just before 12.1-55.291
Citrix ADC and Citrix Gateway versions 13.1 are not impacted. The company also said there are no workarounds obtainable “past disabling SAML authentication or upgrading to a present-day make.”
The virtualization solutions supplier mentioned it’s conscious of a “modest selection of targeted attacks in the wild” working with the flaw, urging prospects to apply the most current patch to unmitigated programs.
APT5, also recognised as Bronze Fleetwood, Keyhole Panda, Manganese, and UNC2630, is believed to run on behalf of Chinese interests. Past year, Mandiant unveiled espionage action targeting verticals that aligned with government priorities outlined in China’s 14th 5-Year Plan.
All those attacks entailed the abuse of a then-disclosed flaw in Pulse Secure VPN equipment (CVE-2021-22893, CVSS score: 10.) to deploy destructive web shells and exfiltrate useful facts from business networks.
“APT5 has demonstrated capabilities towards Citrix Application Delivery Controller deployments,” NSA reported. “Targeting Citrix ADCs can facilitate illegitimate accessibility to specific corporations by bypassing regular authentication controls.”
Microsoft, very last month, pointed out Chinese danger actors’ background of identifying and using zero days to their edge right before getting picked up by other adversarial collectives in the wild.
News of the Citrix bug also comes a day soon after Fortinet exposed a significant vulnerability that also facilitates distant code execution in FortiOS SSL-VPN products (CVE-2022-42475, CVSS score: 9.3).
VMWare releases updates for code execution vulnerabilities
In a connected improvement, VMware disclosed aspects of two critical flaws impacting ESXi, Fusion, Workstation, and vRealize Network Perception (vRNI) that could consequence in command injection and code execution.
- CVE-2022-31702 (CVSS rating: 9.8) – Command injection vulnerability in vRNI
- CVE-2022-31703 (CVSS rating: 7.5) – Directory traversal vulnerability in vRNI
- CVE-2022-31705 (CVSS rating: 5.9/9.3) – Heap out-of-bounds generate vulnerability in EHCI controller
“On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is put in,” the business reported in a security bulletin for CVE-2022-31705.
