Researchers have released additional details about the recently patched four vulnerabilities affecting Juniper Networks' SRX firewalls and EX switches that could allow remote code execution, as well as a proof-of-concept exploit. Earlier this month, Juniper Networks published an out-of-cycle security bulletin notifying customers using its SRX firewalls and EX switches of vulnerabilities that, chained together, would allow attackers to remotely execute code on vulnerable appliances.

Lazarus Group exploited ManageEngine vulnerability to target critical infrastructureNorth Korean state-sponsored hackers Lazarus Group have been exploiting a ManageEngine ServiceDesk vulnerability to target internet backbone infrastructure and healthcare institutions in Europe and the US. Maintaining consistent security in diverse cloud infrastructuresIn this Help Net Security interview, Kennedy Torkura, CTO at Mitigant, discusses the complexity of maintaining clear visibility into cloud environments, why it poses such a challenge for CISOs, and how they can prepare to address potential issues. IEEE 802.11az provides security enhancements, solves longstanding problemsIn this Help Net Security interview, Jonathan Segev, IEEE 802.11 Task Group Chair of next-generation positioning at IEEE, discusses IEEE 802.11az.

Juniper Networks has fixed four vulnerabilities in Junos OS that, if chained together, could allow attackers to achieve remote code execution on the company's SRX firewalls and EX switches.Junos OS is an operating system based on Linux and FreeBSD that runs on Juniper Networks firewalls, network switches and other security devices.

Millions of PLC used in industrial environments worldwide are at risk to 15 vulnerabilities in the CODESYS V3 software development kit, allowing remote code execution and denial of service attacks. Over 500 device manufacturers use the CODESYS V3 SDK for programming on more than 1,000 PLC models according to the IEC 61131-3 standard, allowing users to develop custom automation sequences.

Microsoft today released a defense-in-depth update for Microsoft Office that prevents exploitation of a remote code execution vulnerability tracked as CVE-2023-36884 that threat actors have already leveraged in attacks. In today's Microsoft August Patch Tuesday, the update helps fix CVE-2023-36884, a security issue disclosed in July, which Microsoft did not patch at the time but provided mitigation advice.

Ai researchers have published some details about CVE-2023-39143, two vulnerabilities in PaperCut application servers that could be exploited by unauthenticated attackers to execute code remotely. They noted, unlike the PaperCut vulnerability recently leveraged by Clop and LockBit ransomware affiliates, CVE-2023-39143 is not a "One-shot" RCE bug.

PaperCut recently fixed a critical security vulnerability in its NG/MF print management software that allows unauthenticated attackers to gain remote code execution on unpatched Windows servers. While it only impacts servers in non-default configurations where the external device integration setting is toggled, Horizon3 said in a report published on Friday that most Windows PaperCut servers have it enabled.

Hackers are actively exploiting a 'BleedingPipe' remote code execution vulnerability in Minecraft mods to run malicious commands on servers and clients, allowing them to take control of the devices. BleedingPipe is a vulnerability found in many Minecraft mods caused by the incorrect use of deserialization in the 'ObjectInputStream' class in Java to exchange network packets between servers and clients.

Thousands of Citrix Netscaler ADC and Gateway servers exposed online are likely vulnerable against a critical remote code execution bug exploited by unauthenticated attackers in the wild as a zero-day. "We tag all IPs where we see a version hash in a Citrix instance. This is due fact that Citrix has removed version hash information in recent revisions," Shadowserver said.

Threat actors have breached the network of a U.S. organization in the critical infrastructure sector after exploiting a zero-day RCE vulnerability currently identified as CVE-2023-3519, a critical-severity issue in NetScaler ADC and Gateway that Citrix patched this week.Because the targeted NetScaler ADC appliance was in a segregated environment on the network, the hackers were not able to move laterally to a domain controller, CISA says.
