It emphasizes the potential consequences of exploits in background systems and showcases how XML External Entity (XXE) vulnerabilities can be leveraged across different platforms. #Chrome #Vulnerabilities #EmbeddedSystems

Keypoints :

  • Browsers such as Chrome are used in many devices beyond traditional computers, including smart TVs, e-readers, and embedded systems.
  • Vulnerabilities like CVE-2023-4357 (XXE flaw in Chrome) can be exploited to read local files and leak sensitive data from affected devices.
  • Many legacy or embedded devices run outdated Chrome versions, making them susceptible to such vulnerabilities even years after discovery.
  • Exploiting these vulnerabilities can involve injecting malicious content into server-side or embedded HTML, SVG, or JavaScript environments.
  • Attackers can automate extraction of data, such as passwords or configuration files, by sending malicious requests and retrieving the output.
  • Understanding whether the target is using a native browser or a bundled embedded one is crucial for successful exploitation.
  • Creative attack methods include exploiting internal navigation flows or using social engineering to trigger payloads on restricted devices.
