Name of the Vulnerable Software and Affected Versions: SAP NetWeaver versions 2004s, 7.01 SR1, 7.02 SP06, and 7.30 SP04 Description: A Buffer Overflow issue exists in the Message Server service, specifically in the MsJ2EE AddStatistics() function, when it processes specially crafted SAP Message Server packets sent to remote TCP ports. This could allow a remote malicious user to execute arbitrary code. Recommendations: For SAP NetWeaver version 2004s, update to a version that includes the fix for this issue. For SAP NetWeaver version 7.01 SR1, update to a version that includes the fix for this issue. For SAP NetWeaver version 7.02 SP06, update to a version that includes the fix for this issue. For SAP NetWeaver version 7.30 SP04, update to a version that includes the fix for this issue. As a temporary workaround, consider restricting access to the MsJ2EE AddStatistics() function in the Message Server service until a patch is available.

The issue is a Heap Based Buffer Overflow that can be exploited with a crafted CAR archive file from an untrusted remote source. The problem arises because the length of data written is determined by an arbitrary number found within the file.

The issue allows context-dependent attackers to obtain sensitive configuration information by leveraging knowledge of a hardcoded encryption key used to protect stored data.

The issue allows remote attackers to cause a denial of service, resulting in a program crash, by including an invalid file name in an archive file. This occurs because SAP SAPCAR does not check the return value of file operations when extracting files.

The issue allows local users to change the permissions of arbitrary files and gain privileges via a hard link attack on files extracted from an archive.

The issue is related to a stack-based buffer overflow in the LZC decompression implementation, specifically in the `CsObjectInt::CsDecomprLZC` function. This can be exploited by attackers to cause a denial of service or possibly execute arbitrary code. The exploitation vectors are not specified.

The issue allows context-dependent attackers to cause a denial of service via unspecified vectors, related to look-ups of non-simple codes in the LZH decompression implementation, specifically in the CsObjectInt::BuildHufTree function.

The issue is related to the Web interface not properly handling sessions. This allows remote authenticated users to obtain sensitive information from other users' sessions by making a large number of requests.

The issue allows remote attackers to obtain passwords via a brute-force attack that relies on timing differences in responses to incorrect password guesses, also known as a timing side-channel attack. This occurs because the `passwordCheck` function terminates validation of a Route Permission Table entry password upon encountering the first incorrect character.
