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.

Adobe warns that a critical ColdFusion pre-authentication remote code execution vulnerability tracked as CVE-2023-29300 is actively exploited in attacks. CVE-2023-29300 is rated as critical with a 9.8 severity rating, as it can be used by unauthenticated visitors to remotely execute commands on vulnerable Coldfusion 2018, 2021, and 2023 servers in low-complexity attacks.

Rockwell Automation says a new remote code execution exploit linked to an unnamed Advanced Persistent Threat group could be used to target unpatched ControlLogix communications modules commonly used in manufacturing, electric, oil and gas, and liquified natural gas industries.The company teamed up with the U.S. Cybersecurity and Infrastructure Security Agency to analyze the exploit linked to APT threat actors, but they have yet to share how they obtained it.
