CISA Adds Two Vulnerabilities in N-able N-central to Its Known Exploited Vulnerabilities Catalog

Aug 14, 2025 | Vulnerability / Network Security

On Wednesday, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) included two security flaws affecting N-able N-central in its Known Exploited Vulnerabilities (KEV) catalog, due to evidence of active exploitation. N-able N-central is a Remote Monitoring and Management (RMM) platform tailored for Managed Service Providers (MSPs) to effectively manage and safeguard their clients’ Windows, Apple, and Linux endpoints from a centralized platform.

The identified vulnerabilities are as follows:

  • CVE-2025-8875 (CVSS score: N/A): An insecure deserialization vulnerability that may allow for command execution.
  • CVE-2025-8876 (CVSS score: N/A): A command injection vulnerability resulting from improper sanitization of user input.

Both issues have been resolved in N-central versions 2025.3.1 and 2024.6 HF2, released on August 13, 2025. N-able is also advising customers to ensure multi-factor authentication (MFA) is enabled, particularly for admin accounts.

Urgent: New Chrome 0-Day Vulnerability Under Active Exploitation – Update Your Browser Immediately!

On March 3, 2021, just a month after addressing an actively exploited zero-day flaw, Google has released updates for another critical vulnerability in Chrome, which is reportedly being targeted by attackers. The latest version, Chrome 89.0.4389.72, available for Windows, Mac, and Linux, includes a total of 47 security enhancements. The most severe issue addresses an “object lifecycle problem in audio,” tracked as CVE-2021-21166. This vulnerability was among two reported by Alison Huffman of Microsoft Browser Vulnerability Research on February 11. A separate audio-related object lifecycle flaw was reported to Google on February 4, coinciding with the launch of Chrome 88. Though details are limited, it’s unclear whether the two issues are interconnected. Google has confirmed the existence of exploits in the wild but hasn’t provided further specifics. Users are urged to update their browsers without delay.

New Vulnerabilities May Allow Hackers to Bypass Spectre Mitigations on Linux

Cybersecurity researchers have recently unveiled two critical vulnerabilities in Linux-based systems. If exploited, these flaws could enable attackers to bypass mitigations for speculative execution attacks like Spectre and access sensitive kernel memory. Identified by Piotr Krysiuk from Symantec’s Threat Hunter team, the vulnerabilities are designated as CVE-2020-27170 and CVE-2020-27171, both with a CVSS score of 5.5. They affect all Linux kernels released before version 5.11.8. Security patches were made available on March 20, with various distributions, including Ubuntu, Debian, and Red Hat, implementing fixes. CVE-2020-27170 can disclose content from any kernel memory location, while CVE-2020-27171 enables data retrieval from a 4GB segment of kernel memory. First reported in January 2018, the Spectre and Meltdown vulnerabilities exploit weaknesses in modern CPUs to leak sensitive data.

Urgent: Update Your Chrome Browser Immediately to Fix Recently Discovered Vulnerability

Google has released a critical update for the Chrome web browser across Windows, Mac, and Linux, addressing seven security issues, including one actively exploited flaw. Identified as CVE-2021-21224, this vulnerability arises from a type confusion problem in the V8 JavaScript engine, reported by security researcher Jose Martinez on April 5. Security expert Lei Cao explains that the bug occurs during integer type conversion, leading to an out-of-bounds condition that could allow arbitrary memory read/write access. “Google is aware of reports indicating that exploits for CVE-2021-21224 are in the wild,” stated Chrome’s Technical Program Manager, Srinivas Sista, in a recent blog post. This update follows the release of proof-of-concept code by a researcher named “frust” on April 14, highlighting the urgency of addressing this issue.
