Descriptions

Vulnerability in the Oracle Outside In Technology component of Oracle Fusion Middleware (subcomponent: Outside In Filters). The supported version that is affected are 8.5.3 and 8.5.4. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Outside In Technology. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of Oracle Outside In Technology accessible data. Note: Outside In Technology is a suite of software development kits (SDKs). The protocol and CVSS score depend on the software that uses the Outside In Technology code. The CVSS score assumes that the software passes data received over a network directly to Outside In Technology code, but if data is not received over a network the CVSS score may be lower. CVSS 3.0 Base Score 4.3 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N).

Vulnerabilidad en el componente Oracle Outside In Technology de Oracle Fusion Middleware (subcomponente: Outside In Filters). Las versiones compatibles que se han visto afectadas son la 8.5.3 y la 8.5.4. Una vulnerabilidad fácilmente explotable permite que un atacante sin autenticar que tenga acceso a red por HTTP comprometa la seguridad de Oracle Outside In Technology. Para que los ataques tengan éxito, se necesita la participación de otra persona diferente del atacante. Los ataques exitosos a esta vulnerabilidad pueden resultar en un acceso de lectura sin autorización a un subconjunto de datos accesibles de Oracle Outside In Technology. Nota: Outside In Technology es una suite de kits de desarrollo de software (SDK). La puntuación de protocolo y de CVSS depende del software que emplea el código Outside In Technology. La puntuación CVSS asume que el software pasa datos recibidos a través de una red directamente en código Outside In Technology, pero si los datos no se reciben a través de una red, la puntuación CVSS podría ser menor. CVSS 3.0 Base Score 4.3 (Impactos de confidencialidad). Vector CVSS: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N).

This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Oracle Outside In. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within vsxl5.dll. When parsing the GelFrame record, the process does not properly validate user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this vulnerability to disclose sensitive information in the context of the current process.
