Horizon Alert

Summary of the vulnerability and why it matters

The JBoss Seam 2 component within JBoss Enterprise Application Platform is susceptible to issues with how it processes user inputs. This flaw allows for the execution of arbitrary code when specially crafted inputs are provided through a URL. The primary concern arises when the Java Security Manager is not configured correctly, creating a pathway for attackers.

  • Vulnerable component: JBoss Seam 2
  • Core weakness: Improper input sanitization
  • Main business impact: Arbitrary code execution

Attack Path

How an attacker could exploit the issue

This vulnerability exists in JBoss Seam 2, an application development framework. When not properly secured, it allows attackers to execute arbitrary code by sending specially crafted URLs. This can lead to unauthorized control over affected systems and potential data breaches. The vulnerability is exploited when the Java Security Manager is not configured correctly.

  • Systems are exposed externally.
  • Attackers send crafted URLs.
  • Arbitrary code execution results.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could permit attackers to execute arbitrary code on affected systems by exploiting a flaw in how certain inputs are processed. The risk is amplified when the Java Security Manager is not correctly configured, as this bypasses a critical security control. Organizations using the impacted JBoss Enterprise Application Platform versions should consider this a significant threat.

  • Attackers with low skill can exploit.
  • No special access conditions needed.
  • High business risk and urgency.

Priority actions

Operational Fix

Recommended remediation, mitigation, and detection steps

This vulnerability in JBoss Enterprise Application Platform and related products could allow remote attackers to execute arbitrary code. This risk is present when the Java Security Manager is not properly configured. Organizations should take action to identify and mitigate exposure to this vulnerability.

  • Find affected assets.
  • Reduce exposure or isolate risk.
  • Fix, verify, and monitor.

Frequently asked questions

What is JBoss Enterprise Application Platform and JBoss Seam 2?

JBoss Enterprise Application Platform is a software suite for developing and deploying enterprise Java applications. JBoss Seam 2, a component within this platform, streamlines development by integrating Java technologies to build complex, data-driven web applications. It is particularly relevant when used with Red Hat Enterprise Linux.

How does CVE-2010-1871 allow code execution?

CVE-2010-1871 is a vulnerability stemming from improper input sanitization (CWE-917) in JBoss Seam 2. This weakness allows remote attackers to execute arbitrary code by sending specially crafted URLs that exploit flaws in how the Java Expression Language (EL) expressions are processed. This issue is critical when the Java Security Manager is not properly configured.

What is the trigger path and scope for CVE-2010-1871?

Attackers can trigger this vulnerability by sending crafted URLs that exploit how JBoss Seam 2 processes inputs containing Java Expression Language (EL) expressions. The scope is not negated as the vulnerability allows remote attackers to execute arbitrary code. However, exploitation is dependent on the Java Security Manager not being properly configured.

What is the relevance of CVE-2010-1871 given the Halo Surface Signal?

The Halo Surface Signal indicates this vulnerability is likely exploitable because JBoss Enterprise Application Platform and related management products are often web-based and network-exposed, making them reachable. The vulnerability allows remote code execution, which is a significant concern for systems accessible over a network.

What steps should be taken to address CVE-2010-1871?

Organizations should identify all affected assets, reduce their exposure, and isolate any identified risks. Implementing fixes and verifying their effectiveness, followed by continuous monitoring, are essential operational responses. This vulnerability poses a high business risk and requires urgent attention, especially if the Java Security Manager is not correctly configured.
