Dell EMC PV ME5, a tool used for managing Dell servers, contains a vulnerability that could allow hackers to desynchronize a user’s browser connection.

The client-side desync vulnerability affects versions ME5.1.0.0.0 and ME5.1.0.1.0 of Dell EMC PV ME5. It has a CVSS score of 8.1, meaning it is considered a high severity issue.

An unauthenticated attacker could potentially exploit this vulnerability to force a victim’s browser to disconnect from the Dell EMC PV ME5 website. This is done by desynchronizing the browser connection through a specially crafted request.

Once the connection is desynced, it can lead to other attacks like cross-site scripting (XSS) or denial of service (DoS). XSS allows execution of malicious code on the victim’s browser, while DoS makes the website or server unavailable to legitimate users.

To protect themselves, users should update their Dell EMC PV ME5 installation to the latest version as soon as updates are available. They should also be cautious of any suspicious requests or pop-ups on the website. Following basic cybersecurity practices like avoiding untrusted links and websites can also help prevent exploitation of such vulnerabilities.
