Summary
Cisco Jabber Desktop and Mobile Client Software Vulnerabilities

Notes

Summary
Multiple vulnerabilities in Cisco Jabber for Windows, Jabber for MacOS, and Jabber for mobile platforms could allow an attacker to execute arbitrary programs on the underlying operating system (OS) with elevated privileges or gain access to sensitive information. For more information about these vulnerabilities, see the Details ["#details"] section of this advisory. Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities. This advisory is available at the following link: https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-jabber-ZktzjpgO ["https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-jabber-ZktzjpgO"]
Vulnerable Products
These vulnerabilities affect Cisco Jabber for Windows, Jabber for MacOS and Jabber for mobile platforms. For information about which Cisco software releases are vulnerable, see the Fixed Software ["#fs"] section of this advisory.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products ["#vp"] section of this advisory are known to be affected by these vulnerabilities.
Details
The vulnerabilities are not dependent on one another. Exploitation of one of the vulnerabilities is not required to exploit another vulnerability. In addition, a software release that is affected by one of the vulnerabilities may not be affected by the other vulnerabilities. Details about the vulnerabilities are as follows: Cisco Jabber Message Handling Vulnerabilities To exploit the two following message handling vulnerabilities, an attacker must be able to send Extensible Messaging and Presence Protocol (XMPP) messages to end-user systems running Cisco Jabber. Attackers may require access to the same XMPP domain or another method of access to be able to send messages to clients. As a result of exploitation, an attacker could cause the application to run an arbitrary executable that already exists within the local file path of the application. The executable would run on the end-user system with the privileges of the user who initiated the Cisco Jabber client application. Systems using Cisco Jabber in phone-only mode without XMPP messaging services enabled are not vulnerable to exploitation. In addition, the vulnerability is not exploitable when Cisco Jabber is configured to use messaging services other than XMPP messaging. Cisco Jabber Message Handling Arbitrary Program Execution Vulnerability A vulnerability in Cisco Jabber for Windows and Cisco Jabber for MacOS could allow an authenticated, remote attacker to execute programs on a targeted system. The vulnerability is due to improper validation of message contents. An attacker could exploit this vulnerability by sending specially crafted XMPP messages to the affected software. A successful exploit could allow the attacker to cause the application to execute arbitrary programs on the targeted system with the privileges of the user account that is running the Cisco Jabber client software, possibly resulting in arbitrary code execution. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability. CVE ID: CVE-2020-26085 Bug ID(s): CSCvv88490 ["https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvv88490"] Security Impact Rating (SIR): Critical CVSS Base Score: 9.9 CVSS Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H ["https://sec.cloudapps.cisco.com/security/center/cvssCalculator.x?version=3.1&vector=CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"] Cisco Jabber Message Handling Script Injection Vulnerability A vulnerability in Cisco Jabber for Windows, MacOS, and mobile platforms could allow an authenticated, remote attacker to inject arbitrary script and potentially execute arbitrary commands on some platforms. The vulnerability is due to improper validation of message contents. An attacker could exploit this vulnerability by sending specially crafted XMPP messages to the affected software. By convincing a targeted user to interact with a message, an attacker could inject arbitrary script code within the Jabber message window interface. A successful exploit could allow the attacker to cause the application on MacOS or Windows platforms to execute arbitrary programs on the targeted system with the privileges of the user account that is running the Cisco Jabber client software, possibly resulting in arbitrary code execution. A successful exploit on mobile platforms could allow the attacker to run a script to modify the application interface or obtain information from the Jabber application. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

The vulnerability is due to improper handling of input to the application protocol handlers. An attacker could exploit this vulnerability by convincing a user to click a link within a message sent by email or other messaging platform. A successful exploit could allow the attacker to execute arbitrary commands on a targeted system with the privileges of the user account that is running the Cisco Jabber client software. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

The vulnerability is due to improper validation of message contents. An attacker could exploit this vulnerability by sending specially crafted messages to a targeted system. A successful exploit could allow the attacker to cause the application to return sensitive authentication information to another system, possibly for use in further attacks. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

There are no workarounds that address these vulnerabilities.
Fixed Software
Cisco has released free software updates that address the vulnerabilities described in this advisory. Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license: https://www.cisco.com/c/en/us/products/end-user-license-agreement.html ["https://www.cisco.com/c/en/us/products/end-user-license-agreement.html"] Additionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades. When considering software upgrades ["https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page ["https://www.cisco.com/go/psirt"], to determine exposure and a complete upgrade solution. In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers. Customers Without Service Contracts Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC: https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html ["https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html"] Customers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade. Fixed Releases Customers are advised to upgrade to an appropriate fixed software release as indicated in the following tables: Cisco Jabber for Windows Release First Fixed Release Earlier than 12.1.
