Functional code that demonstrates an exploit of the VMware vCenter Chargeback Manager ImageUploadServlet remote code execution vulnerability is publicly available.
VMware vCenter Chargeback Manager contains a vulnerability that could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system.
The vulnerability is due to insufficient security restrictions imposed on user-supplied input by the affected software. An unauthenticated, remote attacker could exploit the vulnerability by issuing requests via malicious files. Processing of such requests could allow the attacker to execute arbitrary code on a targeted system.
Functional code that exploits this vulnerability is available as part of the Metasploit framework.
VMware has confirmed the vulnerability and released updated software.
VMware vCenter Chargeback Manager versions 2.01 and 2.5 are vulnerable.
To exploit the vulnerability, the attacker may need to be able to access the application in order to send file upload requests to the targeted system. This access requirement could limit the possibility of an exploit.
VMware has released a security advisory at the following link: VMSA-2013-0008
An unauthenticated, remote attacker could exploit this vulnerability to execute arbitrary code on the targeted system.
The vulnerability is due to improper handling of file upload requests by the ImageUploadServlet of the affected software.
An unauthenticated, remote attacker could exploit this vulnerability by sending crafted file upload requests to the vulnerable servlet. Processing of such requests could allow the attacker to create malicious files at arbitrary locations. This ability could allow the attacker to execute arbitrary code via created files with SYSTEM level privileges.
Administrators are advised to apply the appropriate updates.
Administrators are advised to allow only trusted users to have network access.
Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.
Administrators are advised to monitor affected systems.
The security vulnerability applies to the following combinations of products.
