SecurityTracker Alert ID:  1035578
SecurityTracker URL:  http://securitytracker.com/id/1035578
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Apr 15 2016
Impact:   Denial of service via network, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of system information, Modification of user information, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): Enterprise 5.0.x, 6.x prior to 6.0.11, 6.1.10, 6.2.9, 6.3.3.4; Light 6.2.x prior to 6.2.9, 6.3.x prior to 6.3.3.4
Description:   Multiple vulnerabilities were reported in Splunk. A remote user can cause denial of service conditions on the target system. A remote user can bypass security controls on the target system. A remote authenticated user can access and overwrite files on the target system. A remote authenticated user can obtain potentially sensitive information on the target system. A remote authenticated user can execute arbitrary code on the target system.

A remote user can send an HTTP header with a specially crafted header component to Splunk Web to cause denial of service conditions. The vendor has assigned SPL-102960, SPL-102961, SPL-102241, and SPL-103926 to this vulnerability.

Splunk Enterprise versions prior to 5.0.15, 6.0.11, 6.1.10, and 6.2.7 are affected.

A remote user can send a specially crafted HTTP request to Splunk Web to cause denial of service conditions. The vendor has assigned SPL-106804, SPL-106800, SPL-103822, SPL-106803, and SPL-106805 to this vulnerability.

Splunk Enterprise versions prior to 5.0.15, 6.0.11, 6.1.10, 6.2.7, and 6.3.2 are affected.

A remote authentiated user can exploit a direct object access flaw in Splunk Search to access search logs. The vendor has assigned SPL-107199, SPL-107197, SPL-107196, SPL-107123, and SPL-116567 to this vulnerability.

The system does not honor the target user's TLS protocol selection (i.e., sslVersions keyword). A remote user can bypass TLS protocol policies. The vendor has assigned SPL-108213 and SPL-115292 to this vulnerability.

Splunk Enterprise versions prior to 5.0.15 and 6.0.11 are affected.

A remote authenticated user can exploit a path traversal flaw in the collect command to execute arbitrary code on the target system. The code will run with the privileges of the splunkd process. The vendor has assigned SPL-112516, SPL-112517, SPL-112518, SPL-112519, and SPL-114842 to this vulnerability.

A remote authenticated user can exploit a path traversal flaw in the inputcsv and outputcsv commands to access and overwrite arbitrary file paths. The vendor has assigned SPL-115074, SPL-115075, SPL-115076, SPL-115077, and SPL-115217 to this vulnerability.

Franz G. Jahn SySS GmbH reported this vulnerability.

Impact:   A remote authenticated user can access and overwrite files on the target system.
