Synopsis

The remote host has a web application running that is affected by multiple vulnerabilities.

Description

The Advantech WebAccess application running on the remote host is prior to version 8.1-2015.12.30. It is, therefore, affected by multiple vulnerabilities :

- An information disclosure vulnerability exists due to the storage of email project accounts in plaintext. A remote attacker can exploit this to disclose sensitive information about email project accounts. (CVE-2015-3943)

- A cross-site request forgery vulnerability exists due to a failure to require multiple steps, explicit confirmation, or a unique token when performing sensitive actions. A remote attacker can exploit this, by convincing a user to follow a specially crafted link, to hijack the authentication of users. (CVE-2015-3946)

- A SQL injection vulnerability exists due to improper sanitization of user-supplied input before using it in SQL queries. A remote, authenticated attacker can exploit this to inject or manipulate SQL queries to the back-end database, resulting in the manipulation or disclosure of arbitrary data. (CVE-2015-3947)

- A cross-site scripting vulnerability exists due to improper validation of input before returning it to users. A remote, authenticated attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session. (CVE-2015-3948)

- A remote code execution vulnerability exists in the browser plugin due to improper sanitization of input to file names and paths. A remote attacker can exploit this to execute arbitrary code. (CVE-2015-6467)

- A remote code execution vulnerability exists due to a format string flaw in BwOpcSvc.dll that is triggered as format string specifiers (e.g. %s and %x) are not properly provided when handling IOCTL 0x13881. A remote attacker can exploit this, via a specially crafted request to the webvrpcs service, to execute arbitrary code. (CVE-2016-0851)

- An unspecified flaw exists due to improper access control. A remote attacker can exploit this to gain access to arbitrary files and folders. (CVE-2016-0852)

- An information disclosure vulnerability exists due to an unspecified input validation flaw. A remote attacker can exploit this to disclose sensitive information. (CVE-2016-0853)

- Multiple remote code execution vulnerabilities exist due to improper validation of file types and extensions by the UploadAjaxAction, SaveGeneralFile, and FileUpload scripts. A remote attacker can exploit these issues to upload arbitrary files and execute them with SYSTEM privileges. (CVE-2016-0854) - Multiple path traversal and file overwrite vulnerabilities exist in the Dashboard Viewer due to improper sanitization of user-supplied input in the renameFolder, addFolder, removeFolder, removeFile, and openWidget scripts. A remote attacker can exploit these issues, via a specially crafted request, to rename or overwrite arbitrary files and folders. (CVE-2016-0855)

- Multiple remote code execution vulnerabilities exist due to improper validation of user-supplied input when handling IOCTL calls. A remote attacker can exploit these issues, via a specially crafted request to the webvrpcs or datacore service, to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-0856)

- Multiple remote code execution vulnerabilities exist due to improper validation of user-supplied input when handling IOCTL calls. A remote attacker can exploit these issues, via a specially crafted request to the webvrpcs or datacore service, to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-0857)

- A remote code execution vulnerability exists due to improper validation of user-supplied input when handling IOCTL 0x7920. A remote attacker can exploit this, via a specially crafted request to the datacore service, to cause a stack-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-0858)

- A remote code execution vulnerability exists due to improper validation of user-supplied input when handling IOCTL 0x791E. A remote attacker can exploit this, via a specially crafted request to the datacore service, to cause an integer overflow condition, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-0859)

- Multiple remote code execution vulnerabilities exist due to improper validation of user-supplied input when handling IOCTL 0x11172 and 0x11173. A remote attacker can exploit these issues, via a specially crafted request to the webvrpcs service, to cause a buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2016-0860)
