Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 0.47% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Versa Director and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: Within 3 daysRemediation target: Within 90 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

What, why and how

The Versa Director software exposes a number of services by default and allow attackers an easy foothold due to default credentials and multiple accounts (most with sudo access) that utilize the same default credentials. By default, Versa director exposes ssh and postgres to the internet, alongside a host of other services. Versa Networks is not aware of any reported instance where this vulnerability was exploited. Proof of concept for this vulnerability has been disclosed by third party security researchers. Workarounds or Mitigation: Versa recommends the following security controls: 1) Change default passwords to complex passwords 2) Passwords must be complex with at least 8 characters that comprise of upper case, and lower case alphabets, as well as at at least one digit, and one special character 3) Passwords must be changed at least every 90 days 4) Password change history is checked to ensure that the at least the last 5 passwords must be used when changing password. 5) Review and audit logs for all authentication attempts to check for unauthorized/suspicious login attempts and enforce remediation steps.

Why

The product initializes or sets a resource with a default that is intended to be changed by the product's installer, administrator, or maintainer, but the default is not secure.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Likely attack path
a network path → Initialization of a Resource with an Insecure Default → cause the confidentiality, integrity or availability impact described by the vendor

CWE-1188: Initialization of a Resource with an Insecure Default. The product initializes or sets a resource with a default that is intended to be changed by the product's installer, administrator, or maintainer, but the default is not secure.

JVN iPedia · Japanese · JVNDB-2025-026263Versa Networks, Inc.のVersa Directorにおけるリソースの安全ではないデフォルト値への初期化に関する脆弱性

Versa Directorソフトウェアはデフォルトで複数のサービスを公開しており、デフォルトの資格情報および同じデフォルト資格情報を使用する複数のアカウント(ほとんどがsudoアクセス権を持っています)によって、攻撃者が簡単に足掛かりを得られる状態になっています。デフォルトでは、Versa Directorはsshおよびpostgresをインターネットに公開しており、その他多数のサービスも同様に公開されています。Versa Networksは、この脆弱性が悪用されたという報告事例を把握していません。この脆弱性に関する概念実証は、第三者のセキュリティ研究者によって公開されています。回避策または緩和策として、Versaは以下のセキュリティ対策を推奨しています。1) デフォルトパスワードを複雑なパスワードに変更すること。2) パスワードは8文字以上で、大文字と小文字のアルファベット、少なくとも1つの数字、1つの特殊文字を含む複雑なものにすること。3) パスワードは少なくとも90日ごとに変更すること。4) パスワード変更時に過去5回分のパスワード履歴を確認し、同じパスワードが再利用されないようにすること。5) すべての認証試行のログをレビューおよび監査し、不正または疑わしいログイン試行を検出して是正措置を実施すること。
