SAP Business Objects Business Intelligence Platform (Crystal Reports), versions- 4.1, 4.2, allows an attacker with basic authorization to inject code that can be executed by the application and thus allowing the attacker to control the behaviour of the application, leading to Remote Code Execution. Although the mode of attack is only Local, multiple applications can be impacted as a result of the vulnerability.
Weakness
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
