Detail

a. VMware vCenter Server LDAP Denial of Service (DoS)

VMware vCenter Server doesn't correctly handle specially crafted LDAP network packets which may allow for remote DoS.

VMware would like to thank Honggang Ren of Fortinet's FortiGuard Labs for reporting this issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the identifier CVE-2017-4927 to this issue.

Column 5 of the following table lists the action required to remediate the vulnerability in each release, if a solution is available.

b. SSRF and CRLF injection issues in vSphere Web client

The Flash-based vSphere Web Client (i.e. not the new HTML5-based vSphere Client) contains server side request forgery (SSRF) and CRLF injection issues due to improper neutralization of URLs. An attacker may exploit these issues by sending a POST request with modified headers towards internal services leading to information disclosure.

VMware would like to thank ricterzheng @ Tencent Yunding Lab for reporting this issue to us.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the identifier CVE-2017-4928 to this issue.
