How Vulnerabilities Lead to Breaches: Analyzing 5 Real-World Examples

đź“… April 28, 2025
Cloud Security / Vulnerability

Not all security vulnerabilities pose a high risk on their own, but in the hands of skilled attackers, even minor weaknesses can escalate into significant breaches. This article highlights five real vulnerabilities identified by Intruder’s bug-hunting team, illustrating how attackers exploit overlooked flaws to create serious security incidents.

  1. Compromising AWS Credentials via Redirects
    Server-Side Request Forgery (SSRF) is a prevalent vulnerability that can have severe consequences, particularly in cloud environments. If a web application retrieves resources from user-provided URLs, it’s crucial to prevent attackers from manipulating requests to access unauthorized resources. During our evaluation of a home-moving application hosted on AWS, our team explored common SSRF bypass techniques. The attack unfolded as follows: the application sent a webhook request to the attacker’s server, which responded with a 302 redirect to AWS’s metadata service. The application followed the redirect and logged the response, inadvertently exposing sensitive metadata…

Understanding the Genesis of Breaches: Analyzing Five Real Vulnerabilities April 28, 2025 In the realm of cybersecurity, not every vulnerability is inherently catastrophic. However, when exploited by skilled attackers, even minor weaknesses can culminate in significant breaches. Recent findings from…

Critical 10-Year Vulnerability in Roundcube Webmail Allows Code Execution by Authenticated Users

On June 3, 2025, cybersecurity researchers revealed a significant security flaw in Roundcube webmail software, active for a decade, that could enable authenticated users to execute malicious code on vulnerable systems. Classified as CVE-2025-49113, the vulnerability has a CVSS score of 9.9 out of 10, highlighting its severity. It involves post-authentication remote code execution through PHP object deserialization. According to the National Vulnerability Database (NVD), “Roundcube Webmail versions before 1.5.10 and 1.6.x prior to 1.6.11 allow authenticated users to execute remote code due to the lack of validation for the _from parameter in the URL in program/actions/settings/upload.php.” This flaw affects all versions up to and including 1.6.10 but has been patched in versions 1.6.11 and 1.5.10 LTS. The vulnerability was discovered and reported by Kirill Firsov, founder and CEO of FearsOff.

Critical Vulnerability in Roundcube Webmail Exposes Systems to Remote Code Execution On June 3, 2025, cybersecurity researchers revealed a significant security vulnerability in the Roundcube webmail software, a flaw that has remained undetected for a decade. This vulnerability has the…

Meta Exposes Extensive Cyber Espionage Campaigns on Social Media in South Asia

May 04, 2023
Social Media / Cyber Risk

Three distinct threat actors exploited countless elaborate fake profiles on Facebook and Instagram to conduct targeted attacks against individuals in South Asia. “These advanced persistent threats (APTs) relied heavily on social engineering tactics to deceive users into clicking malicious links, downloading malware, or sharing sensitive information online,” stated Guy Rosen, Meta’s chief information security officer. “This focus on social engineering reduced their need to invest heavily in malware development.” The counterfeit accounts utilized traditional tactics, pretending to be romantic interests, recruiters, journalists, or military personnel. Notably, two cyber espionage initiatives involved low-sophistication malware, likely attempting to evade app verification measures from Apple and Google. Meta’s findings revealed…

Meta Uncovers Extensive Cyber Espionage Campaigns Targeting South Asia On May 4, 2023, Meta revealed the discovery of a significant cyber espionage operation involving multiple threat actors utilizing a network of fraudulent identities on Facebook and Instagram. These campaigns aimed…

CISA Adds Critical Broadcom and Commvault Vulnerabilities to KEV Database

April 29, 2025
Vulnerability / Web Security

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) announced on Monday that two serious security vulnerabilities affecting Broadcom’s Brocade Fabric OS and Commvault’s Web Server have been added to its Known Exploited Vulnerabilities (KEV) database, following reports of active exploitation. The specific vulnerabilities are:

  • CVE-2025-1976 (CVSS score: 8.6) – A code injection vulnerability in Broadcom Brocade Fabric OS that permits a local user with administrative rights to execute arbitrary code with full root access.
  • CVE-2025-3928 (CVSS score: 8.7) – An unspecified flaw in the Commvault Web Server that enables a remote, authenticated attacker to create and execute web shells. Commvault’s advisory from February 2025 noted, “Exploiting this vulnerability requires the attacker to have authenticated user credentials within the Commvault Software environment. Unauthenticated access is not exploitable. For software customers, this means your organization must …”

CISA Integrates Broadcom and Commvault Vulnerabilities into KEV Database On April 29, 2025, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) fortifies its Known Exploited Vulnerabilities (KEV) catalog by including two critical security flaws affecting Broadcom’s Brocade Fabric OS and…

HPE Releases Security Patch for StoreOnce Vulnerability Allowing Remote Authentication Bypass

U.S. Government Dismantles Russia’s Advanced Snake Cyber Espionage Tool

May 10, 2023
Cyber Espionage / Cyber Attack

On Tuesday, the U.S. government announced the successful court-authorized disruption of a global network compromised by an advanced malware strain known as Snake, utilized by Russia’s Federal Security Service (FSB). Referred to as the “most sophisticated cyber espionage tool,” Snake is attributed to the Russian state-sponsored group Turla (also known as Iron Hunter, Secret Blizzard, SUMMIT, Uroburos, Venomous Bear, and Waterbug), connected to a unit within Center 16 of the FSB. This threat actor has historically targeted entities in Europe, the Commonwealth of Independent States (CIS), and NATO-affiliated countries, with recent efforts expanding into Middle Eastern nations viewed as threats to Russian-supported interests in the region. “For nearly 20 years, this unit […] has leveraged versions of the Snake malware to steal sensitive documents from hundreds of computer systems in at least 50 countries…”
