As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco Crosswork engineering team has conducted a comprehensive internal security review. This review resulted in a software hardening release that addresses multiple internally discovered vulnerabilities.
The vulnerabilities tracked by CVE-2026-20358 are related to external control of the file system issues that are grouped Common Weakness Enumeration (CWE) CWE-73.
AnalysisAI
External control of file system paths (CWE-73) in Cisco Crosswork Planning versions 7.0.0 through 7.2.0 allows a remote, unauthenticated attacker to influence file names or paths used by the application, yielding high integrity and availability impact with a scope change (CVSS 10.0). The flaw was discovered internally by Cisco during a proactive hardening review and disclosed as part of a bundled software hardening advisory; no public exploit identified at time of analysis and it is not listed in CISA KEV. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Per the CVSS vector (AV:N/AC:L/PR:N/UI:N), no authentication, no user interaction, and only low complexity are required, so exploitation is remote and unauthenticated against a network-reachable Cisco Crosswork Planning instance running any version from 7.0.0 through 7.2.0. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine top-priority issue on the raw signals: CVSS 3.1 base score is 10.0 with AV:N/AC:L/PR:N/UI:N, meaning network-reachable, low-complexity, unauthenticated exploitation with a scope change. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Patch available per vendor advisory: upgrade Cisco Crosswork Planning to the fixed hardening release identified in Cisco Security Advisory cisco-sa-hardening-crosswork-UzDTU9Vh (https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-hardening-crosswork-UzDTU9Vh); the exact fixed version string is not included in the provided data and must be read from that advisory, so do not assume a version number. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all instances of Cisco Crosswork Planning running versions 7.0.0 through 7.2.0 in your environment and document their network exposure, criticality, and business dependencies. …
