Citrix Issues Critical Patches for 11 New Flaws Affecting Multiple Products

Citrix Issues Critical Patches for 11 New Flaws Affecting Multiple Products

Jul 08, 2020
Citrix yesterday issued new security patches for as many as 11 security flaws that affect its Citrix Application Delivery Controller (ADC), Gateway, and SD-WAN WAN Optimization edition (WANOP) networking products. Successful exploitation of these critical flaws could let unauthenticated attackers perform code injection, information disclosure, and even denial-of-service attacks against the gateway or the authentication virtual servers . Citrix confirmed that the aforementioned issues do not impact other virtual servers, such as load balancing and content switching virtual servers. Among the affected Citrix SD-WAN WANOP appliances include models 4000-WO, 4100-WO, 5000-WO, and 5100-WO. The networking vendor also reiterated that these vulnerabilities were not connected to a previously fixed zero-day NetScaler flaw (tagged as CVE-2019-19781 ) that allowed bad actors to perform arbitrary code execution even without proper authentication. It also said there's no evidence
Citrix Releases Patches for Critical ADC Vulnerability Under Active Attack

Citrix Releases Patches for Critical ADC Vulnerability Under Active Attack

Jan 20, 2020
Citrix has finally started rolling out security patches for a critical vulnerability in ADC and Gateway software that attackers started exploiting in the wild earlier this month after the company announced the existence of the issue without releasing any permanent fix. I wish I could say, "better late than never," but since hackers don't waste time or miss any opportunity to exploit vulnerable systems, even a short window of time resulted in the compromise of hundreds of Internet exposed Citrix ADC and Gateway systems. As explained earlier on The Hacker News, the vulnerability, tracked as CVE-2019-19781 , is a path traversal issue that could allow unauthenticated remote attackers to execute arbitrary code on several versions of Citrix ADC and Gateway products, as well as on the two older versions of Citrix SD-WAN WANOP. Rated critical with CVSS v3.1 base score 9.8, the issue was discovered by Mikhail Klyuchnikov, a security researcher at Positive Technologies, w

How to Accelerate Vendor Risk Assessments in the Age of SaaS Sprawl

Mar 21, 2024SaaS Security / Endpoint Security
In today's digital-first business environment dominated by SaaS applications, organizations increasingly depend on third-party vendors for essential cloud services and software solutions. As more vendors and services are added to the mix, the complexity and potential vulnerabilities within the  SaaS supply chain  snowball quickly. That's why effective vendor risk management (VRM) is a critical strategy in identifying, assessing, and mitigating risks to protect organizational assets and data integrity. Meanwhile, common approaches to vendor risk assessments are too slow and static for the modern world of SaaS. Most organizations have simply adapted their legacy evaluation techniques for on-premise software to apply to SaaS providers. This not only creates massive bottlenecks, but also causes organizations to inadvertently accept far too much risk. To effectively adapt to the realities of modern work, two major aspects need to change: the timeline of initial assessment must shorte

It's now or never to prevent your enterprise servers running vulnerable versions of Citrix application delivery, load balancing, and Gateway solutions from getting hacked by remote attackers. Why the urgency? Earlier today, multiple groups publicly released weaponized proof-of-concept exploit code [ 1 , 2 ] for a recently disclosed remote code execution vulnerability in Citrix's NetScaler ADC and Gateway products that could allow anyone to leverage them to take full control over potential enterprise targets. Just before the last Christmas and year-end holidays, Citrix announced that its Citrix Application Delivery Controller (ADC) and Citrix Gateway are vulnerable to a critical path traversal flaw (CVE-2019-19781) that could allow an unauthenticated attacker to perform arbitrary code execution on vulnerable servers. Citrix confirmed that the flaw affects all supported version of the software, including: Citrix ADC and Citrix Gateway version 13.0 all supported build
