Details
The Cisco Internet Streamer application provides edge caching, content streaming, and downloads to subscriber IP devices such as PCs. This includes the password files used to hold admin account details and system logs.
This vulnerability can be exploited over all open HTTP ports; TCP ports 80 (Default HTTP port), 443 (Default HTTPS port) and 8090 (Alternate HTTP and HTTPS port), as well as those that are configured as part of the HTTP proxy.
In Cisco content delivery system software 2.5.3 and earlier, it is possible to configure "Enable Incoming Proxy", which when enabled, accepts incoming requests on configured ports, in addition to TCP port 80. The additional ports that the device will listen on for HTTP requests is defined in the "List of Incoming HTTP Ports" field, within "Devices > Devices > Application Control > Web > HTTP > HTTP Connections" of the content delivery system manager menu. For further information on HTTP settings, refer to the "Cisco Internet Streamer CDS 2.5 Software Configuration Guide - Configuring Devices" at the following link:
http://www.cisco.com/en/US/docs/video/cds/cda/is/2_5/configuration_guide/configdevice.html.
This vulnerability is documented in the Cisco Bug ID CSCtd68063 and has been assigned Common Vulnerabilities and Exposures (CVE) ID CVE-2010-1577.

Workarounds
Service Rules +------------
As an interim step prior to upgrading the Cisco content delivery system software, it is possible to deny access to sensitive directories via service rules. The following example shows denying access to move up a directory level. This also caters for other directory moves, such as "../", "../" or "../":
rule enable
rule action block pattern-list 1
rule pattern-list 1 url-regex ^http://.*/../.*
rule pattern-list 1 url-regex ^https://.*/../.*
For more information on configuring service rules and for instructions on how to perform this via the content delivery system manager, consult the Cisco Internet Streamer CDS 2.5 Software Configuration Guide at the following link:
http://www.cisco.com/en/US/docs/video/cds/cda/is/2_5/configuration_guide/configdevice.html#wp1773573.

On the same line of output, the version number will\nbe provided. \n Content Delivery System Software Release 2.5.3 (build b8 Jan 21 2010)\n Version: cde200-2.5.3.8\n\n Compiled 16:07:11 Jan 21 2010 by ipvbuild\n Compile Time Options: KQ SS\n\n System was restarted on Thu Jun 3 04:09:25 2010. \n The system has been up for 2 hours, 11 minutes, 27 seconds. \n\n cdn-cde#\n\nAlternatively the Content Delivery System Manager home page gives a\nbrief summary of the software versions in use on all the devices in the\ncontent delivery system network. \n\nTo view the software version running on a particular device, choose\n\"Devices \u003e Devices\". The Devices Table page displays the software\nversion for each device listed. For further information on finding the\nsoftware version, refer to the \"Maintaining the Internet Streamer CDS\"\nat the following link:\n\nhttp://www.cisco.com/en/US/docs/video/cds/cda/is/2_5/configuration_guide/maint.html#wp1198510. \n\nNo other Cisco products are currently known to be affected by this\nvulnerability. \n\nDetails\n=======\n\nThe Cisco Internet Streamer application provides edge caching, content\nstreaming, and downloads to subscriber IP devices such as PCs. This includes the password\nfiles used to hold admin account details and system logs. \n\nThis vulnerability can be exploited over all open HTTP ports; TCP ports\n80 (Default HTTP port), 443 (Default HTTPS port) and 8090 (Alternate\nHTTP and HTTPS port), as well as those that are configured as part of\nthe HTTP proxy. \n\nIn Cisco content delivery system software 2.5.3 and earlier, it is\npossible to configure \"Enable Incoming Proxy\", which when enabled,\naccepts incoming requests on configured ports, in addition to TCP\nport 80. The additional ports that the device will listen on for\nHTTP requests is defined in the \"List of Incoming HTTP Ports\" field,\nwithin \"Devices \u003e Devices \u003e Application Control \u003e Web \u003e HTTP \u003e HTTP\nConnections\" of the content delivery system manager menu. For further\ninformation on HTTP settings, refer to the \"Cisco Internet Streamer CDS\n2.5 Software Configuration Guide - Configuring Devices\" at the following\nlink:\n\nhttp://www.cisco.com/en/US/docs/video/cds/cda/is/2_5/configuration_guide/configdevice.html. \n\nThis vulnerability is documented in the Cisco Bug ID CSCtd68063 and\nhas been assigned Common Vulnerabilities and Exposures (CVE) ID\nCVE-2010-1577. \n\nVulnerability Scoring Details\n+----------------------------\n\nCisco has provided scores for the vulnerability in this advisory based\non the Common Vulnerability Scoring System (CVSS). The CVSS scoring in\nthis Security Advisory is done in accordance with CVSS version 2.0. \n\nCVSS is a standards-based scoring method that conveys vulnerability\nseverity and helps determine urgency and priority of response. \n\nCisco has provided a base and temporal score. Customers can then\ncompute environmental scores to assist in determining the impact of the\nvulnerability in individual networks. \n\nCisco has provided an FAQ to answer additional questions regarding CVSS\nat:\n\nhttp://www.cisco.com/web/about/security/intelligence/cvss-qandas.html\n\nCisco has also provided a CVSS calculator to help compute the\nenvironmental impact for individual networks at:\n\nhttp://intellishield.cisco.com/security/alertmanager/cvss\n\n* CSCtd68063 (\"CDS Internet Streamer: Web Server Directory Traversal\nVulnerability\")\n\nCVSS Base Score - 7.8\n Access Vector - Network\n Access Complexity - Low\n Authentication - Single\n Confidentiality Impact - Complete\n Integrity Impact - None\n Availability Impact - None\n\nCVSS Temporal Score - 6.4\n Exploitability - Functional\n Remediation Level - Official-Fix\n Report Confidence - Confirmed\n\n\nImpact\n======\n\nAn unauthenticated attacker may be able to exploit this issue to access\nsensitive information, including the password files and system logs,\nwhich could be leveraged to launch subsequent attacks. \n\nSoftware Versions and Fixes\n===========================\n\nWhen considering software upgrades, also consult\nhttp://www.cisco.com/go/psirt and any subsequent advisories to determine\nexposure and a complete upgrade solution. \n\nIn all cases, customers should exercise caution to be certain the\ndevices to be upgraded contain sufficient memory and that current\nhardware and software configurations will continue to be supported\nproperly by the new release. If the information is not clear, contact\nthe Cisco Technical Assistance Center (TAC) or your contracted\nmaintenance provider for assistance. \n\nThe recommended release contains other software fixes that are\nrecommended by Cisco. For further information please consult the release\nnotes at the following link:\n\nhttp://www.cisco.com/en/US/docs/video/cds/cda/is/2_5/release_notes/CDS_RelNotes2_5_9.html#wp100128\n\n+---------------------------------------+\n| Cisco | | |\n| Content | | |\n| Delivery | First Fixed | Recommended |\n| System | Release | Release |\n| Software | | |\n| Release | | |\n|-----------+-------------+-------------|\n| | Vulnerable, | |\n| 2.2.x | Migrate to | |\n| | 2.5.7 or | |\n| | later | |\n|-----------+-------------+-------------|\n| | Vulnerable, | |\n| 2.3.x | Migrate to | |\n| | 2.5.7 or | |\n| | later | |\n|-----------+-------------+-------------|\n| | Vulnerable, | |\n| 2.4.x | Migrate to | |\n| | 2.5.7 or | |\n| | later | |\n|-----------+-------------+-------------|\n| 2.5.x | 2.5.7 | 2.5.9 |\n+---------------------------------------+\n\n\nWorkarounds\n===========\n\nService Rules\n+------------\n\nAs an interim step prior to upgrading the Cisco content delivery system\nsoftware, it is possible to deny access to sensitive directories via\nservice rules. The following example shows denying access to move up a\ndirectory level. This also caters for other directory moves, such as\n\"\\.\\./\", \".\\./\" or \"\\../\":\n\n rule enable\n rule action block pattern-list 1\n rule pattern-list 1 url-regex ^http://.*/../.*\n rule pattern-list 1 url-regex ^https://.*/../.*\n\nFor more information on configuring service rules and for instructions\non how to perform this via the content delivery system manager, consult\nthe Cisco Internet Streamer CDS 2.5 Software Configuration Guide at the\nfollowing link:\n\nhttp://www.cisco.com/en/US/docs/video/cds/cda/is/2_5/configuration_guide/configdevice.html#wp1773573. \n\n\nObtaining Fixed Software\n========================\n\nCisco has released free software updates that address this\nvulnerability.
