CVE-2010-3032 in Crystal Reports
Summary
by MITRE
Integer overflow in the OBGIOPServerWorker::extractHeader function in the ebus-3-3-2-6.dll module in SAP Crystal Reports 2008 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a GIOP packet with a crafted size, which triggers a heap-based buffer overflow.

The vulnerability described in CVE-2010-3032 represents a critical security flaw in SAP Crystal Reports 2008 that stems from an integer overflow condition within the OBGIOPServerWorker::extractHeader function. This issue resides in the ebus-3-3-2-6.dll module, which handles communication protocols for the reporting application. The flaw manifests when processing GIOP (General Inter-ORB Protocol) packets, which are used for communication between distributed objects in CORBA environments. The vulnerability specifically occurs when a crafted GIOP packet contains an improperly sized field that triggers an integer overflow during header extraction, ultimately leading to heap-based buffer overflow conditions.
The technical exploitation of this vulnerability involves crafting a malicious GIOP packet with a deliberately manipulated size field that, when processed by the vulnerable function, causes integer arithmetic to wrap around and produce a value that exceeds the bounds of the allocated buffer. This integer overflow condition results in memory corruption where the application attempts to write data beyond the intended buffer boundaries, creating a heap-based buffer overflow scenario. The vulnerability's impact is twofold as it can lead to both denial of service through application crashes and potential code execution if the overflow can be carefully controlled to overwrite critical memory locations.
From an operational perspective, this vulnerability presents significant risks to organizations utilizing SAP Crystal Reports 2008 in their business environments, particularly those that process external data or communicate with untrusted sources. The remote attack vector means that adversaries can exploit this flaw without requiring local access or authentication, making it particularly dangerous in networked environments. The potential for arbitrary code execution adds an additional layer of risk beyond simple service disruption, as attackers could potentially gain full control of affected systems. This vulnerability aligns with CWE-190, which specifically addresses integer overflow conditions, and falls under ATT&CK technique T1203, related to exploitation of remote services through network-based attacks.
Organizations should implement immediate mitigations including applying the official SAP patches and updates that address this specific vulnerability, as well as implementing network segmentation to limit exposure to untrusted networks. Additional protective measures should include monitoring network traffic for suspicious GIOP packet patterns, implementing intrusion detection systems that can identify malformed CORBA communications, and restricting external access to systems running vulnerable versions of SAP Crystal Reports. The vulnerability also underscores the importance of maintaining current security patches and conducting regular vulnerability assessments to identify and remediate similar issues in legacy software components that may continue to operate in enterprise environments despite their age.
