Cybersecurity Alert: Critical Flaws Exposed Today!

Daily Cybersecurity Briefing: From Router Flaws to Web Server Vulnerabilities

Good morning, cybersecurity enthusiasts! In today’s roundup, we’ve spotted a series of critical vulnerabilities targeting devices and software that many businesses—and even federal systems—heavily rely upon. From router flaws actively under exploitation to web server vulnerabilities allowing DoS attacks, here’s what you need to know to keep your digital environment secure.

Router Vulnerabilities in the Spotlight

A recent immediate alert by CISA has confirmed that a flaw (CVE-2023-33538) affecting TP-Link routers is under active exploit. In tandem, similar router flaws from Zyxel are wreaking havoc, with hackers exploiting a critical remote code execution (RCE) vulnerability to target Zyxel firewall and VPN devices globally. These vulnerabilities remind us that even everyday networking equipment can be a potential gateway for cyber intrusions, necessitating urgent firmware updates.

Apache Tomcat: A New Target for Cyber Attacks

Apache Tomcat, a widely utilised web server, is also facing its share of issues. Several high-severity flaws now expose systems to denial-of-service (DoS) attacks, privilege escalation and even potential authentication bypass. This highlights the ongoing challenge in keeping server software hardened against relentless probing by cyber criminals.

TOTOLINK and D-Link Buffer Overflow Vulnerabilities

A concerning series of buffer overflow vulnerabilities have been uncovered in TOTOLINK devices with CVE IDs ranging from CVE-2025-6165 to CVE-2025-6146 and others. These flaws, affecting various models (such as X15, A3002R, A3002RU and EX1200T), allow remote attackers to manipulate HTTP POST request handlers. Similarly, D-Link DIR-665 is not spared, with a critical vulnerability leading to stack-based buffer overflow. The repeated pattern across these devices underscores the importance of regular security assessments and patch management.

Emerging Threats: Langflow and the Flodrix Botnet

Cyber adversaries are not slowing down. A critical vulnerability in Langflow (CVE-2025-3248) is being actively exploited to deploy the Flodrix botnet—a rapidly evolving threat that can lead to full system compromise, DDoS attacks, and data exfiltration. This attack vector exemplifies how rapidly vulnerabilities can be weaponised once they’re discovered, urging organisations to monitor for new updates constantly.

Other Notable Vulnerabilities & Global Cyber Concerns

Among other headlines, financial services, particularly the insurance industry, are being increasingly targeted by threat actors following operations that previously hit retailers and even federal systems. Meanwhile, a series of issues in libxml2 (including denial-of-service and use-after-free vulnerabilities) further emphasise the criticality of secure input processing in common libraries.

In a different turn of events, deceptive fake terror alerts have been witnessed in Israel, reminding us that cyber threats often blend into broader socio-political tactics designed to spread panic. Additionally, cybersecurity investments are clearly on the rise with UK businesses reportedly generating an estimated £27bn in additional revenue thanks to enhanced cyber defences.
