New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis
An enterprise management application installed on the remote host is affected by multiple vulnerabilities.
Description
The version of Oracle Enterprise Manager Grid Control installed on the remote host is missing a security patch. It is, therefore, affected by multiple vulnerabilities :
- A flaw exists in the Bouncy Castle Java library due to improper validation of a point within the elliptic curve. An unauthenticated, remote attacker can exploit this to obtain private keys by using a series of specially crafted elliptic curve Diffie-Hellman (ECDH) key exchanges, also known as an 'invalid curve attack.' (CVE-2015-7940)
- A flaw exists in the PathTools module for Perl in the File::Spec::canonpath() function that is triggered as strings are returned as untainted even when passing tainted input. An unauthenticated, remote attacker can exploit this to pass unvalidated user input to sensitive or insecure areas. (CVE-2015-8607)
- An overflow condition exists in Perl in the MapPathA() function due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2015-8608)
- A remote code execution vulnerability exists in the Apache Struts component due to improper handling of multithreaded access to an ActionForm instance. An unauthenticated, remote attacker can exploit this, via a specially crafted multipart request, to execute arbitrary code or cause a denial of service condition.
(CVE-2016-1181)
- A flaw exists in Perl that is triggered during the handling of variables that appear twice in the environment (envp), causing the last value to appear in %ENV, while getenv would return the first. An unauthenticated, remote attacker can exploit this to cause variables to be incorrectly propagated to subprocesses, regardless of the protections offered by taint checking. (CVE-2016-2381)
- A denial of service vulnerability exists in the Apache Commons FileUpload component due to improper handling of boundaries in content-type headers when handling file upload requests. An unauthenticated, remote attacker can exploit this to cause processes linked against the library to become unresponsive. (CVE-2016-3092)
- A man-in-the-middle vulnerability exists in various components, known as 'httpoxy', due to a failure to properly resolve namespace conflicts in accordance with RFC 3875 section 4.1.18. The HTTP_PROXY environment variable is set based on untrusted user data in the 'Proxy' header of HTTP requests. The HTTP_PROXY environment variable is used by some web client libraries to specify a remote proxy server. An unauthenticated, remote attacker can exploit this, via a crafted 'Proxy' header in an HTTP request, to redirect an application's internal HTTP traffic to an arbitrary proxy server where it may be observed or manipulated.
(CVE-2016-5385, CVE-2016-5386, CVE-2016-5387, CVE-2016-5388)
- A carry propagating error exists in the OpenSSL component in the x86_64 Montgomery squaring implementation that may cause the BN_mod_exp() function to produce incorrect results. An unauthenticated, remote attacker with sufficient resources can exploit this to obtain sensitive information regarding private keys.
Moreover, the attacker would additionally need online access to an unpatched system using the target private key in a scenario with persistent DH parameters and a private key that is shared between multiple clients. For example, this can occur by default in OpenSSL DHE based SSL/TLS cipher suites. (CVE-2017-3732)
- An unspecified flaw exists in the UI Framework component that allows authenticated, remote attacker to have an impact on integrity. (CVE-2017-10091)
Solution
Apply the appropriate patch according to the July 2017 Oracle Critical Patch Update advisory.
