CVE-2009-0899 in WebSphere Application Server
Summary
by MITRE
IBM WebSphere Application Server (WAS) 6.1 through 6.1.0.24 and 7.0 through 7.0.0.4, IBM WebSphere Portal Server 5.1 through 6.0, and IBM Integrated Solutions Console (ISC) 6.0.1 do not properly set the IsSecurityEnabled security flag during migration of WebSphere Member Manager (WMM) to Virtual Member Manager (VMM) and a Federated Repository, which allows attackers to obtain sensitive information from repositories via unspecified vectors.

The vulnerability described in CVE-2009-0899 represents a critical security flaw in IBM WebSphere Application Server and related products that affects versions ranging from WebSphere Application Server 6.1 through 6.1.0.24 and 7.0 through 7.0.0.4, along with WebSphere Portal Server 5.1 through 6.0 and IBM Integrated Solutions Console 6.0.1. This issue stems from improper handling of security flags during the migration process from WebSphere Member Manager to Virtual Member Manager and Federated Repository configurations. The flaw specifically involves the failure to correctly set the IsSecurityEnabled security flag, creating a persistent security gap that can be exploited by malicious actors.
The technical implementation of this vulnerability occurs during the migration phase when WebSphere Member Manager components are transitioned to Virtual Member Manager and Federated Repository architectures. During this process, the IsSecurityEnabled flag that controls security enforcement mechanisms is not properly configured, resulting in a weakened security posture where authentication and authorization controls may be bypassed or improperly enforced. This misconfiguration allows attackers to potentially access sensitive repository information through unspecified attack vectors that leverage the improperly configured security settings.
The operational impact of this vulnerability extends beyond simple information disclosure, as it fundamentally undermines the security architecture of affected systems. Attackers can exploit this weakness to gain unauthorized access to user credentials, application data, and other sensitive repository information that should be protected by the security mechanisms. The vulnerability affects organizations running IBM WebSphere products in production environments, potentially exposing critical business data and compromising the integrity of enterprise applications. The unspecified vectors suggest that attackers may be able to leverage multiple attack surfaces, making the vulnerability particularly dangerous.
Security controls for this vulnerability align with CWE-284, which addresses improper access control in software systems, and specifically relates to the improper handling of security configuration during system transitions. The weakness demonstrates characteristics consistent with ATT&CK technique T1078 which involves valid accounts and privileges, as attackers could potentially leverage the improperly configured security settings to gain elevated access. Organizations should implement immediate mitigations including applying the relevant IBM security patches, reviewing and validating security configurations during migration processes, and implementing additional monitoring controls to detect unauthorized access attempts. The vulnerability highlights the critical importance of proper security flag management during system upgrades and migrations, emphasizing that security configurations must be carefully validated throughout the entire deployment lifecycle to prevent such persistent security weaknesses from being introduced into production environments.
