CVE-2017-3837 — Cisco Meeting Server security vulnerability

High CVSS 8.1

An HTTP Packet Processing vulnerability in the Web Bridge interface of the Cisco Meeting Server (CMS), formerly Acano Conferencing Server, could allow an authenticated, remote attacker to retrieve memory contents, which could lead to the disclosure of confidential information. In addition, the attacker could potentially cause the application to crash unexpectedly, resulting in a denial of service (DoS) condition. The attacker would need to be authenticated and have a valid session with the Web Bridge. Affected Products: This vulnerability affects Cisco Meeting Server software releases prior to 2.1.2. This product was previously known as Acano Conferencing Server. More Information: CSCvc89551. Known Affected Releases: 2.0 2.0.7 2.1. Known Fixed Releases: 2.1.2.

Matched remediation archetype

Resource exhaustion and denial of service

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
  • Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
  • Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.

Remediate safely

  • Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
  • Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
  • Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
