CVE-1999-1136: Vulnerability in Predictive on HP-UX 11.0 and earlier, and MPE/iX 5.5 and earlier, allows attackers
Vulnerability in Predictive on HP-UX 11.0 and earlier, and MPE/iX 5.5 and earlier, allows attackers to compromise data transfer for Predictive messages (using e-mail or modem) between customer and Response Center Predictive systems.
AI Analysis
Technical Summary
CVE-1999-1136 is a medium severity vulnerability affecting the Predictive software running on HP-UX 11.0 and earlier versions, as well as MPE/iX 5.5 and earlier. This vulnerability allows attackers to compromise the confidentiality, integrity, and availability of data transfers involving Predictive messages exchanged between customers and the Response Center Predictive systems. The data transfer mechanisms impacted include communication via email or modem connections. Specifically, the vulnerability is categorized under CWE-200, which relates to information exposure, indicating that sensitive data could be disclosed to unauthorized parties. The CVSS score of 4.6 reflects a medium risk level, with the attack vector being local (AV:L), low attack complexity (AC:L), no authentication required (Au:N), and impacts on confidentiality, integrity, and availability (C:P/I:P/A:P). Since the attack vector is local, exploitation requires the attacker to have some level of access to the affected system, but no authentication is needed, which lowers the barrier for exploitation once local access is obtained. The vulnerability is historical, published in 1998, and no patches are available, which suggests that affected systems may be legacy or no longer supported. No known exploits are reported in the wild, but the lack of patching and the potential for sensitive data compromise remain concerns for organizations still operating these environments. The vulnerability primarily impacts legacy HP systems running MPE/iX or HP-UX operating systems, which are specialized and less common in modern IT environments but may still be in use in certain industrial or legacy contexts.
Potential Impact
For European organizations, the impact of this vulnerability depends largely on whether they operate legacy HP-UX or MPE/iX systems with Predictive software in their infrastructure. Organizations in sectors such as manufacturing, telecommunications, or utilities that historically relied on HP systems may still have these legacy environments. The vulnerability could lead to unauthorized disclosure of sensitive operational data, manipulation of predictive maintenance messages, or disruption of communication between customers and support centers. This could result in operational downtime, loss of data integrity, and potential exposure of confidential information. Given the local attack vector, the threat is more significant in environments where internal security controls are weak or where insider threats exist. The absence of patches means organizations must rely on compensating controls to mitigate risk. While the vulnerability is medium severity, the potential impact on critical infrastructure or industrial control systems in Europe could be substantial if exploited, especially in sectors where legacy HP systems remain integral to operations.
Mitigation Recommendations
Since no official patches are available for CVE-1999-1136, European organizations should implement the following specific mitigations: 1) Isolate legacy HP-UX and MPE/iX systems running Predictive software from general network access, restricting connectivity to trusted internal networks only. 2) Enforce strict access controls and monitoring on these systems to prevent unauthorized local access, including robust physical security and user account management. 3) Use network segmentation to separate legacy systems from critical business networks and limit communication channels to only necessary endpoints. 4) Employ encryption and secure communication protocols for data transfers where possible, replacing or supplementing legacy email or modem-based communications with more secure alternatives. 5) Conduct regular audits and monitoring for unusual activity on these legacy systems to detect potential exploitation attempts early. 6) Develop and maintain incident response plans specifically addressing legacy system vulnerabilities and potential data compromise scenarios. 7) Where feasible, plan and execute migration strategies to modern, supported platforms to eliminate exposure to unpatchable legacy vulnerabilities.
