CVE-2017-6669: Multiple buffer overflow vulnerabilities exist in the Cisco WebEx Network Recording Player for Advanced Rec...

Multiple buffer overflow vulnerabilities exist in the Cisco WebEx Network Recording Player for Advanced Recording Format (ARF) files. An attacker could exploit these vulnerabilities by providing a user with a malicious ARF file via email or URL and convincing the user to launch the file. Exploitation of these vulnerabilities could cause an affected player to crash and, in some cases, could allow arbitrary code execution on the system of a targeted user. The Cisco WebEx Network Recording Player is an application that is used to play back WebEx meeting recordings that have been recorded on the computer of an online meeting attendee. The player can be automatically installed when the user accesses a recording file that is hosted on a WebEx server. The following client builds are affected by this vulnerability: Cisco WebEx Business Suite (WBS29) client builds prior to T29.13.130, Cisco WebEx Business Suite (WBS30) client builds prior to T30.17, Cisco WebEx Business Suite (WBS31) client builds prior to T31.10. Cisco Bug IDs: CSCvc47758 CSCvc51227 CSCvc51242.

Security readout for executives and security teams

CVE-2017-6669 affects Cisco WebEx Network Recording Player when handling ARF recording files. A malicious recording file sent by email or link could crash the player and may run code on the user’s computer if opened. The risk is user-targeted rather than server-side, but outdated clients should be treated seriously. Organizations are exposed where legacy Cisco WebEx Network Recording Player or affected WebEx Business Suite client builds remain installed on user workstations, especially where users receive or open ARF recordings from email or web links. Prioritize remediation on endpoints that handle meeting recordings or receive external attachments. This is not described as actively exploited in the supplied evidence, but potential code execution on user systems makes outdated clients a high-priority cleanup item. Mitigation focus: Upgrade WBS29 clients to T29.13.130 or later.; Upgrade WBS30 clients to T30.17 or later.; Upgrade WBS31 clients to T31.10 or later..

Improper Restriction of Operations within the Bounds of a Memory Buffer

Improper Restriction of Operations within the Bounds of a Memory Buffer represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
