Evidence used

  • No CISA KEV confirmation is currently recorded.
  • Exploitation requires an existing local or physical foothold with privileges.
  • EPSS is 0.36% for the current model date.

Compensating controls

  • Restrict local access and enforce least privilege on affected hosts.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Cobham plc Explorer 710 and falls inside the recorded affected range.
  2. Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
  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: No default targetRemediation target: Normal maintenance

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.

01

What, why and how

The web root directory of the Cobham EXPLORER 710, firmware version 1.07, has no access restrictions on downloading and reading all files. This could allow an unauthenticated, local attacker connected to the device to access and download any file found in the web root directory.

What

The web root directory of the Cobham EXPLORER 710, firmware version 1.07, has no access restrictions on downloading and reading all files. This could allow an unauthenticated, local attacker connected to the device to access and download any file found in the web root directory.

Why

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

How

An attacker operating through local access may attempt exploitation with low privileges. 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
local access → Improper Access Control → cause the confidentiality, integrity or availability impact described by the vendor

Weakness
?CWE means Common Weakness Enumeration: a standard category for the underlying weakness.
CWE-284 ↗

CWE-284: Improper Access Control. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

CVSS vector
?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.
CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

AVLocalAttack vector: The attacker needs local access to the vulnerable system.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRLowPrivileges required: The attacker needs basic user-level privileges.UINoneUser interaction: No action by another user is required.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.INoneIntegrity impact: No direct loss is represented by this metric.ANoneAvailability impact: No direct loss is represented by this metric.
Post-exploitation / living off the land
The issue can support a local privilege or sandbox boundary transition; normal system utilities may then be available in the gained context.

JVN iPedia · Japanese · JVNDB-2019-010367衛星通信端末 Cobham EXPLORER 710 における複数の脆弱性

Cobham EXPLORER 710 は衛星通信やインターネットアクセスに用いられる携帯用の衛星通信端末です。Cobham EXPLORER 710 には、次の複数の脆弱性が存在します。 CVE-2019-9529 当該製品の Web インターフェースはデフォルト状態において認証を必要としません。そのため、ローカルネットワーク内の攻撃者によって端末の Web ポータルにアクセスされ、設定を変更される可能性があります。 CVE-2019-9530 当該製品のドキュメントルートディレクトリにはアクセス制限がかかっていません。そのため、ローカルネットワーク内の攻撃者により任意のファイルにアクセスされる可能性があります。 CVE-2019-9531 当該製品の 5454/tcp ポートに対して認証なしで telnet 接続が可能であり、また telnet 接続の後、86 種類の Attention (AT) コマンドを実行することが可能です。そのため、遠隔の攻撃者により端末にアクセスされ、これらのコマンドを実行される可能性があります。 CVE-2019-9532 当該製品の Web インターフェースでは、ログインのためのパスワードが平文で送信されます。そのため、ローカルネットワーク内の攻撃者によりパスワード情報が窃取される可能性があります。 CVE-2019-9533 当該製品のファームウェア v1.08 およびそれ以前の全てのバージョンにおいて、同一の root パスワードが用いられています。攻撃者は該当する任意のバージョンのファームウェアを解析することにより、root パスワードを窃取することが可能です。 CVE-2019-9534 当該製品では、ファームウェアイメージの検証が行われません。また、ファームウェア中に残された開発用スクリプトにより、ファームウェアのカスタムイメージをアップロードし実行することが可能です。そのため、ローカルネットワーク内の攻撃者により、改ざんされたファームウェアをインストールされ、通信内容の改変や窃取、バックドアの設置やサービス運用妨害 (DoS) 攻撃等が行われる可能性があります。 なお CERT/CC によると、当該製品についてはこれらの脆弱性の他に、製品のシリアルナンバーがデフォルトの WiFi パスワードがとして設定されているため容易に総当り攻撃が可能であること、またセキュリティに関する重要な HTTP ヘッダがなく、クロスサイトスクリプティングやクリックジャッキング攻撃に対しても脆弱であるとのことです。 これらの脆弱性は 2014年に実施された IOActive’s findings に関する一連の調査として CERT/CC の研究者によって新たに発見されました。
