CVE intelligence and bounded remediation
CVE-2020-1722 — A flaw was found in all ipa versions 4.x.x through 4.8.0
Medium
CVSS 5.4
A flaw was found in all ipa versions 4.x.x through 4.8.0. When sending a very long password (>= 1,000,000 characters) to the server, the password hashing process could exhaust memory and CPU leading to a denial of service and the website becoming unresponsive. The highest threat from this vulnerability is to system availability.

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.
