CVE-2020-37143: ProficySCADA for iOS 5.0.25920 - 'Password' Denial of Service

ProficySCADA for iOS 5.0.25920 contains a denial of service vulnerability that allows attackers to crash the application by manipulating the password input field. Attackers can overwrite the password field with 257 bytes of repeated characters to trigger an application crash and prevent successful authentication.

Analyst readout for executives and security teams

Plain-English summary

A specific ProficySCADA for iOS version can crash when the password field is mishandled. The business impact is likely loss of mobile SCADA access for affected users, not proven compromise of control systems. Treat as important if this app remains in operational use.

Executive priority

Prioritize if mobile SCADA access is used in production or incident response. The likely impact is service disruption for operators using this iOS app. If the app is obsolete or absent, business urgency is low after verification.

Technical view

CVE-2020-37143 affects ProficySCADA for iOS 5.0.25920. Sources describe a password input handling flaw causing application crash and authentication failure. The record lists CWE-770 and CVSS 3.1 score 7.5, AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N.

Likely exposure

Exposure appears limited to organizations still running ProficySCADA for iOS 5.0.25920. Risk is higher where the app’s login path is reachable by untrusted users or networks. No other versions or platforms are identified in the provided sources.

Exploitation context

A public Exploit-DB entry exists, but the CVE is not listed as CISA KEV in the provided bundle. The sources do not establish active exploitation. Details should be handled carefully because the public proof-of-concept may enable reproduction.

Researcher notes

The source description is denial of service, while the supplied CVSS vector indicates high confidentiality impact and no availability impact. That inconsistency should be validated against primary records before scoring decisions. No patch information is present in the provided sources.

Mitigation direction

  • Inventory iOS devices for ProficySCADA version 5.0.25920.
  • Check vendor guidance for fixed versions, retirement status, or recommended replacements.
  • Remove or disable the affected app where it is not operationally required.
  • Restrict access to SCADA mobile workflows to trusted users and networks.

Validation and detection

  • Use MDM or device inventory to identify installed app versions.
  • Confirm whether ProficySCADA for iOS 5.0.25920 is still used operationally.
  • Review mobile access paths for untrusted network reachability.
  • Document compensating controls if no vendor fix is available.
