IBM WebSphere Application Server 7.x before 7.0.0.39, 8.0.x before 8.0.0.11, and 8.5.x before 8.5.5.7 and WebSphere Virtual Enterprise before 7.0.0.7 allow remote attackers to obtain potentially sensitive information about the proxy-server software by reading the HTTP Via header.

The remote host appears to be running IBM WebSphere Application Server 8.5 prior to 8.5.5.7.  Such versions are potentially affected by multiple issues :

 - An information disclosure vulnerability exists that allows an unauthenticated, remote attacker to identify the proxy server software by reading the HTTP 'Via' header. (CVE-2015-1932)
 - An unspecified flaw exists that allows an unauthenticated, remote attacker to spoof servlets or disclose sensitive information. (CVE-2015-4938)

The remote host appears to be running IBM WebSphere Application Server 8.5 prior to 8.5.5.6.  Such versions are potentially affected by multiple issues :

 - A flaw exists that is triggered as deployment descriptor security constraints are combined with ServletSecurity annotations on a servlet. This may allow a remote attacker to gain elevated privileges. (CVE-2014-8890)
 - A security feature bypass vulnerability, known as FREAK (Factoring attack on RSA-EXPORT Keys), exists in the IBM Global Security Kit (GSKit) due to the support of weak EXPORT_RSA cipher suites with keys less than or equal to 512 bits.  A man-in-the-middle (MitM) attacker may be able to downgrade the SSL/TLS connection to use EXPORT_RSA cipher suites which can be factored in a short amount of time, allowing the attacker to intercept and decrypt the traffic. (CVE-2015-0138)
 - An information disclosure vulnerability exists due to a flaw in the Bleichenbacher countermeasure implementation in Apache WSS4J.  A remote attacker can exploit this, via a crafted message, to determine where an encryption failure took place, allowing the attacker to gain access to the plaintext symmetric key. (CVE-2015-0226)
 - An XML External Entity (XXE) vulnerability exists due to an incorrectly configured XML parser that accepts XML external entities from an untrusted source.  A remote attacker can exploit this, via specially crafted XML data, to gain access to arbitrary files. (CVE-2015-0250)
 - A privilege escalation vulnerability exists due to a flaw that occurs in 'full' profile and 'liberty' profile when using an OAuth grant password.  A remote attacker can exploit this to gain elevated privileges. (CVE-2015-1885)
 - A privilege escalation vulnerability exists due to incorrect settings in the 'serveServletsbyClassname' functionality.  A remote attacker can exploit this to gain elevated privileges. (CVE-2015-1927)
 - An information disclosure vulnerability exists that allows an unauthenticated, remote attacker to identify the proxy server software by reading the HTTP 'Via' header. (CVE-2015-1932)
 - An unspecified flaw exists in the administrative console that allows a remote attacker, via the 'JSESSIONID' parameter, to hijack a user's session. (CVE-2015-1936)
 - A privilege escalation vulnerability exists due to an unspecified flaw that occurs when handling user roles.  A local attacker can exploit this to gain elevated privileges. (CVE-2015-1946)
 - A security feature bypass vulnerability exists, known as Bar Mitzvah, due to improper combination of state data with key data by the RC4 cipher algorithm during the initialization phase.  A MitM attacker can exploit this, via a brute-force attack using LSB values, to decrypt the traffic. (CVE-2015-2808)
 - An unspecified flaw exists that allows an unauthenticated, remote attacker to spoof servlets or disclose sensitive information. (CVE-2015-4938)

The IBM HTTP Server running on the remote host is version 6.1 prior to or equal to 6.1.0.47, 7.0 prior to 7.0.0.39, 8.0 prior to 8.0.0.12, or 8.5 prior to 8.5.5.7. It is, therefore, potentially affected by multiple vulnerabilities :

  - An overflow condition exists in the XML_GetBuffer()     function in xmlparse.c due to improper validation of     user-supplied input when handling compressed XML     content. An attacker can exploit this to cause a buffer     overflow, resulting in the execution of arbitrary code.
    (CVE-2015-1283)

  - A denial of service vulnerability exists when processing     an ECParameters structure due to an infinite loop that     occurs when a specified curve is over a malformed binary     polynomial field. A remote attacker can exploit this to     perform a denial of service against any system that     processes public keys, certificate requests, or     certificates. This includes TLS clients and TLS servers     with client authentication enabled. (CVE-2015-1788)

  - An information disclosure vulnerability exists that     allows an unauthenticated, remote attacker to identify     the proxy server software by reading the HTTP 'Via'     header. (CVE-2015-1932)

  - A flaw exists in the chunked transfer coding     implementation due to a failure to properly parse chunk     headers. A remote attacker can exploit this to conduct     HTTP request smuggling attacks. (CVE-2015-3183)

  - An unspecified flaw exists that allows an     unauthenticated, remote attacker to spoof servlets or     disclose sensitive information. (CVE-2015-4938)

  - An overflow condition exists in the Administration     Server due to improper validation of user-supplied     input. An attacker can exploit this, via a specially     crafted request, to cause a stack-based buffer overflow,     resulting in a denial of service condition or the     execution of arbitrary code. (CVE-2015-4947)
