Detected Vulnerabilities and Situations in sgpkg-ips
The table s below shows the weaknesses and high level categories that are related to this weakness. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as PeerOf and CanAlsoBe are defined to show similar weaknesses that the user may want to explore.
The different Modes of Introduction provide information about how and when this weakness may be introduced. The Phase identifies a point in the life cycle at which introduction may occur, while the Note provides a typical scenario related to introduction during the given phase. The table below specifies different individual consequences associated with the weakness. The Scope identifies the application security area that is violated, while the Impact describes the negative technical impact that arises if an adversary succeeds in exploiting this weakness.
The Likelihood provides information about how likely the specific consequence is expected to be seen relative to the other consequences in the list. For example, there may be high likelihood that a weakness will be exploited to achieve a certain impact, but a low likelihood that it will be exploited to achieve a different impact. While buffer overflow examples can be rather complex, it is possible to have very simple, yet still exploitable, stack-based buffer overflows:.
The buffer size is fixed, but there is no guarantee the string in argv will not exceed this size and cause an overflow. This example takes an IP address from a user, verifies that it is well formed and then looks up the hostname and copies it into a buffer. This function allocates a buffer of 64 bytes to store the hostname, however there is no guarantee that the hostname will not be larger than 64 bytes. If an attacker specifies an address which resolves to a very large hostname, then we may overwrite sensitive data or even relinquish control flow to the attacker.
Run or compile the software using features or extensions that automatically provide a protection mechanism that mitigates or eliminates buffer overflows. For example, certain compilers and extensions provide automatic buffer overflow detection mechanisms that are built into the compiled code.
CWE is sponsored by the U. CWE Glossary Definition. Weakness ID: Status: Draft. Presentation Filter:. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack i.
Alternate Terms. Stack Overflow: “Stack Overflow” is often used to mean the same thing as stack-based buffer overflow, however it is also used on occasion to mean stack exhaustion, usually a result from an excessively recursive function call.
Due to the ambiguity of the term, use of stack overflow to describe either circumstance is discouraged. Relevant to the view “Research Concepts” CWE Nature Type ID Name ChildOf Base – a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention.
Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource. Background Details. There are generally several security-critical data on an execution stack that can lead to arbitrary code execution. The most prominent is the stored return address, the memory address at which execution should continue once the current function is finished executing.
The attacker can overwrite this value with some memory address to which the attacker also has write access, into which they place arbitrary code to be run with the full privileges of the vulnerable program. Alternately, the attacker can supply the address of an important call, for instance the POSIX system call, leaving arguments to the call on the stack. This is often called a return into libc exploit, since the attacker generally forces the program to jump at return time into an interesting routine in the C standard library libc.
Other important data commonly on the stack include the stack pointer and frame pointer, two values that indicate offsets for computing memory addresses.
Modifying those values can often be leveraged into a “write-what-where” condition. Modes Of Introduction. Phase Note Architecture and Design Implementation. Applicable Platforms. The listings below show possible areas for which the given weakness could appear. These may be for specific named Languages, Operating Systems, Architectures, Paradigms, Technologies, or a class of such platforms. The platform is listed along with how frequently the given weakness appears for that instance.
Languages C Undetermined Prevalence. Common Consequences. Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the program into an infinite loop. Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of a program’s implicit security policy. When the consequence is arbitrary code execution, this can often be used to subvert any other security service.
Likelihood Of Exploit. Demonstrative Examples. Example 1 While buffer overflow examples can be rather complex, it is possible to have very simple, yet still exploitable, stack-based buffer overflows: bad code. Example Language: C. Potential Mitigations.
Note: This is not necessarily a complete solution, since these mechanisms can only detect certain types of overflows. In addition, an attack could still cause a denial of service, since the typical response is to exit the application. Use an abstraction library to abstract away risky APIs. Not a complete solution. Unless this provides automatic bounds checking, it is not a complete solution.
Do not use dangerous functions such as gets. Use safer, equivalent functions which check for boundary errors. This is not a complete solution. Weakness Ordinalities. Ordinality Description Primary. This information is often useful in understanding where a weakness fits within the context of external information sources.
Characters and Strings STR. Other Stack-based buffer overflows can instantiate in return address overwrites, stack pointer overwrites or frame pointer overwrites. They can also be considered function pointer overwrites, array indexer overwrites or write-what-where condition, etc.
