CVE-2021-21973
MediumCVSS 5.3KEVSummary
The vSphere Client (HTML5) contains an SSRF (Server Side Request Forgery) vulnerability due to improper validation of URLs in a vCenter Server plugin. A malicious actor with network access to port 443 may exploit this issue by sending a POST request to vCenter Server plugin leading to information disclosure.
Risk Assessment
An attacker could gain access to sensitive information, potentially leading to further attacks or security breaches.
Recommendation
Update VMware vCenter Server to version 7.0 U1c, 6.7 U3l, 6.5 U3n or later, and VMware Cloud Foundation to version 4.2, 3.10.1.2 or later.
Other vulnerabilities in VMware vCenter Server
See all- CVE-2017-4927High
VMware vCenter Server versions 6.5 prior to 6.5 U1 and 6.0 prior to 6.0 U3c do not correctly handle specially crafted LDAP network packets, which may allow for remote denial of service.
- CVE-2017-4921High
VMware vCenter Server (6.5 prior to 6.5 U1) contains an insecure library loading issue due to the unsafe use of the LD_LIBRARY_PATH variable. Successful exploitation of this vulnerability may allow unprivileged host users to load a shared library, potentially leading to privilege escalation.
- CVE-2016-7459High
VMware vCenter Server versions 5.5 before U3e and 6.0 before U2a allow remote authenticated users to read arbitrary files via a Log Browser, Distributed Switch setup, or Content Library XML document containing an external entity declaration in conjunction with an entity reference, related to an XML External Entity (XXE) issue.
- CVE-2015-2342High
The JMX RMI service in VMware vCenter Server in versions 5.0 before u3e, 5.1 before u3b, 5.5 before u3, and 6.0 before u1 does not restrict registration of MBeans, allowing remote attackers to execute arbitrary code via the RMI protocol.
- CVE-2024-38813HighActively exploited
Privilege escalation vulnerability in VMware vCenter Server. A malicious actor with network access to vCenter Server may trigger this vulnerability to escalate privileges to root by sending a specially crafted network packet.
- CVE-2023-34048CriticalActively exploited
vCenter Server contains an out-of-bounds write vulnerability in the implementation of the DCERPC protocol. A malicious actor with network access to vCenter Server may trigger an out-of-bounds write potentially leading to remote code execution.
- CVE-2021-22005CriticalActively exploited
