Re: UnrealIRCd 6.2.7 released & hot-patch to fix security issues for existing installations

UnrealIRCd 6.2.7 hot-patch fixes a minor MITM command injection in STARTTLS S2S upgrade, flagged as LLM-reported.

Sam James points to an UnrealIRCd commit fixing a command injection during STARTTLS upgrade in server-to-server links, exploitable only via man-in-the-middle position. He characterizes it as uninteresting and cites it as an example of the typical shape of LLM-reported vulnerability findings.

3 Vulnerabilities Found on AvertX IP Cameras

Unit 42 disclosed three vulnerabilities (CVE-2020-11623/4/5) in AvertX HD838 and 438IR IP cameras; AvertX has released patches.

Palo Alto Networks Unit 42 researchers found three vulnerabilities in AvertX HD838 and 438IR outdoor surveillance cameras, which are rebranded Hikvision products: CVE-2020-11625 (user enumeration), CVE-2020-11624 (weak password requirements), and CVE-2020-11623 (exposed dangerous method/function). User enumeration responses facilitate brute-force attacks, the default admin credentials (admin/1234) are never enforced to change, and physical access to an exposed UART interface allows bootloader access and configuration modification. AvertX released a patch, removed the UART connector, and disabled the interface in the latest production batch.

Understanding Angler Exploit Kit

Unit 42 examines Angler EK operations, including rapid zero-day adoption, fileless Bedep infections, and ransomware payloads like TeslaCrypt and CryptXXX.

Unit 42 published the second part of its Angler EK analysis, covering the kit's history since 2013, its SaaS rental model, and its focus on Flash, Internet Explorer, and Silverlight exploits. Angler integrated the CVE-2015-5119 Flash zero-day from the Hacking Team leak within hours and later added exploits for CVE-2015-2419 and CVE-2016-0034 roughly a month after Microsoft patched them. Campaigns use Angler to deliver ransomware such as CryptoWall, TeslaCrypt, and CryptXXX, plus banking trojans and stealers via EITest. Since August 2014, Angler has used fileless, in-memory execution, most often for Bedep, which later downloads CryptXXX and click-fraud malware.

Microsoft Excel KB5002914 update breaks copy and paste for some users

Microsoft's September Patch Tuesday update KB5002914 breaks copy-and-paste and formula dragging in Excel 2016 through 2024; uninstalling the update restores functionality.

Users on Reddit and Microsoft Q&A report that the KB5002914 security update shipped in the September 2026 Patch Tuesday breaks copy-and-paste, autofill, and formula dragging in Excel. The problem spans Office 2016 through 2024 across MSI and Click-to-Run installations, including Office LTSC Standard 2021, with some teams blocked after widespread patching. Uninstalling KB5002914 or downgrading the Office build restores functionality, though replacing the excel.exe binary is not recommended. BleepingComputer could not reproduce the issue on Excel 2019 Version 2508 Build 19127.20302 and contacted Microsoft for comment.
