Multiple vulnerabilities in the Citrix Application Delivery Controller (ADC) and Gateway would allow code injection, information disclosure and denial of service, the networking vendor announced Tuesday. Four of the bugs are exploitable by an unauthenticated, remote attacker.
The Citrix products (formerly known as NetScaler ADC and Gateway) are used for application-aware traffic management and secure remote access, respectively, and are installed in at least 80,000 companies in 158 countries, according to a December assessment from Positive Technologies.
Other flaws announced Tuesday also affect Citrix SD-WAN WANOP appliances, models 4000-WO, 4100-WO, 5000-WO and 5100-WO.
Attacks on the management interface of the products could result in system compromise by an unauthenticated user on the management network; or system compromise through cross-site scripting (XSS). Attackers could also create a download link for the device which, if downloaded and then executed by an unauthenticated user on the management network, could result in the compromise of a local computer.
“Customers who have configured their systems in accordance with Citrix recommendations [i.e., to have this interface separated from the network and protected by a firewall] have significantly reduced their risk from attacks to the management interface,” according to the vendor.
Threat actors could also mount attacks on Virtual IPs (VIPs). VIPs, among other things, are used to provide users with a unique IP address for communicating with network resources for applications that do not allow multiple connections or users from the same IP address.
The VIP attacks include denial of service against either the Gateway or Authentication virtual servers by an unauthenticated user; or remote port scanning of the internal network by an authenticated Citrix Gateway user.
“Attackers can only discern whether a TLS connection is possible with the port and cannot communicate further with the end devices,” according to the critical Citrix advisory. “Customers who have not enabled either the Gateway or Authentication virtual servers are not at risk from attacks that are applicable to those servers. Other virtual servers e.g. load balancing and content switching virtual servers are not affected by these issues.”
A final vulnerability has been found in Citrix Gateway Plug-in for Linux that would allow a local logged-on user of a Linux system with that plug-in installed to elevate their privileges to an administrator account on that computer, the company said.

Researchers identified serious flaws in Qualcomm’s Snapdragon SoC and the Hexagon architecture that impacts nearly half of Android handsets.
Six serious bugs in Qualcomm’s Snapdragon mobile chipset impact up to 40 percent of Android phones in use, according research released at the DEF CON Safe Mode security conference Friday.
The flaws open up handsets made by Google, Samsung, LG, Xiaomi and OnePlus to DoS and escalation-of-privileges attacks – ultimately giving hackers control of targeted handsets. Slava Makkaveev, a security researcher with Check Point, outlined his discoveryand said while Qualcomm has provided patches for the bug, most OEM handset makers have not yet pushed out the patches.

The faulty Qualcomm component is the mobile chip giant’s Snapdragon SoC and the Hexagon architecture. Hexagon a brand name for Qualcomm’s digital signal processor (DSP), part of the SoC’s microarchitecture. DSP controls the processing of real-time request between the Android user environment and the Snapdragon processor’s firmware – in charge of turning voice, video and services such GPS location sensors into computationally actionable data.
Makkaveev said the DSP flaws can be used to harvest photos, videos, call recordings, real-time microphone data, and GPS and location data. A hacker could also cripple a targeted phone or implant malware that would go undetected.
The six flaws are CVE-2020-11201, CVE-2020-11202, CVE-2020-11206, CVE-2020-11207, CVE-2020-11208 and CVE-2020-11209. Using a fuzzing technique against handsets with the vulnerable chipset, Check Point was able to identify 400 discrete attacks.
The prerequisite for exploiting the vulnerabilities is the target would need to be coaxed into downloading and running a rogue executable.
Qualcomm declined to answer specific questions regarding the bugs and instead issued a statement:
“Providing technologies that support robust security and privacy is a priority for Qualcomm. Regarding the Qualcomm Compute DSP vulnerability disclosed by Check Point, we worked diligently to validate the issue and make appropriate mitigations available to OEMs. We have no evidence it is currently being exploited. We encourage end users to update their devices as patches become available and to only install applications from trusted locations such as the Google Play Store.” – Qualcomm Spokesperson
The flaws were brought to Qualcomm’s attention between February and March. Patches developed by Qualcomm in July. A cursory review of vulnerabilities patched in the July and August Google Android Security Bulletins reveal patches haven’t been yet been pushed to handsets. For that reason, Check Point chose not to reveal technical specifics of the flaws.
What technical details that are available can be found in a DEF CON Safe Mode video posted to online. Here Makkaveev shares some technical specifics.

As icons and rituals adapt to newer technologies, the rise of robotics and AI can change the way we practice and experience spirituality.
**Some 100,000 years ago, fifteen people, eight of them children, were buried on the flank of [Mount Precipice], just outside the southern edge of [Nazareth] in today’s Israel. **One of the boys still held the antlers of a large red deer clasped to his chest, while a teenager lay next to a necklace of seashells painted with ochre and brought from the Mediterranean Sea shore 35 km away. The bodies of Qafzeh are some of the earliest evidence we have of grave offerings, possibly associated with religious practice.
Although some type of _belief _has likely accompanied us from the beginning, it’s not until 50,000–13,000 BCE that we see clear religious ideas take shape in paintings, offerings, and objects.** This is a period filled with Venus figurines, statuettes made of stone, bone, ivory and clay, portraying women with small heads, wide hips, and exaggerated breasts.** It is also the home of the beautiful** lion man**, carved out of mammoth ivory with a flint stone knife and the oldest-known zoomorphic (animal-shaped) sculpture in the world.
We’ve unearthed such representations of primordial gods, likely our first religious icons, all across Europe and as far as Siberia, and although we’ll never be able to ask their creators why they made them, we somehow still feel a connection with the stories they were trying to tell.

Up to now, any robots brushing with the law were always running strictly according to their code. Fatal accidents and serious injuries usually only happened through human misadventure or improper use of safety systems and barriers. We’ve yet to truly test how our laws will cope with the arrival of more sophisticated automation technology — but that day isn’t very far away.
AI already infiltrates our lives on so many levels in a multitude of practical, unseen ways. While the machine revolution is fascinating — and will cause harm to humans here and there — embodied artificial intelligence systems perhaps pose the most significant challenges for lawmakers.
Robots that run according to unchanging code are one thing and have caused many deaths and accidents over the years — not just in the factory but the operating theatre too. Machines that learn as they go are a different prospect entirely — and coming up with laws for dealing with that is likely to be a gradual affair.
Emergent behavior is going to make robots infinitely more effective and useful than they’ve ever been before. The potential danger with emergent behavior is that it’s unpredictable. In the past, robots got programmed for set tasks – and that was that. Staying behind the safety barrier and following established protocols kept operators safe.
