User name without restrictions - critical? Depending on the release of the SAP_BASIS component in your system, invisible special characters may end up in the user name. This is especially critical if only spaces or alternate spaces are used for the user name when creating a new user. In Unicode systems, "alternative" spaces, so-called "wide spaces", can be used in addition to the normal space character (hexadecimal value 20). For example, the key combination "ALT+0160" can be used to insert non-breaking spaces. If a user is now created whose user name consists exclusively of such alternative spaces, this can be confusing. This is because entries for this user ID do appear in change documents, but the impression is created that the entry was created by a non-existent / deleted user. This circumstance can lead to confusion. In addition, certain special characters in the user name can also lead to errors, for example in the Change and Transport System (CTS). This is because the user name is also used in the CTS-ORG to create a file with the same name in the transport directory. Furthermore, there are letters/characters that look identical in different alphabets, but have a different hexadecimal value in the character set. This means that confusion in user names cannot be completely ruled out. Seemingly identical user names then stand for different users.

An important area of SAP Security is the analysis of the customer's own SAP programs, which are classically written in the proprietary SAP language ABAP. Here, too, as in all programming languages, security vulnerabilities can be programmed - whether consciously or unconsciously. However, the patterns of security vulnerabilities in ABAP code differ from those in Java stacks or Windows programs. The goal of these conventional programs is usually to either crash the program (buffer overflow) or to artificially execute the program's own code (code injection). Both is not possible in ABAP, since a crash of a process causes nothing else than the creation of an entry in the log database (Dump ST22) and a subsequent termination of the report with return to the menu starting point. So a direct manipulation as in other high level languages or servers is not possible. However, there are other manipulation possibilities.

Here the existing files are copied into it, namely the cofiles file (K12345_DEV) in the cofiles folder (/usr/sap/trans/cofiles) and the data file (R12345_DEV) in the data folder (/usr/sap/trans/data).
