curl FTP path confusion leads to NIL byte out of bounds write
ghsa·2022-05-14
CVE-2018-1000120 [CRITICAL] CWE-787 curl FTP path confusion leads to NIL byte out of bounds write
curl FTP path confusion leads to NIL byte out of bounds write
curl can be coerced into writing a zero byte out of bounds.
This bug can trigger when curl is told to work on an FTP URL, with the setting to only issue a single CWD command (--ftp-method singlecwd or the libcurl alternative [CURLOPT_FTP_FILEMETHOD](https://curl.se/libcurl/c/CURLOPT_FTP_FILEMETHOD.html)).
curl then URL-decodes the given path, calls strlen() on the result and deducts the length of the file name part to find the end of the directory within the buffer. It then writes a zero byte on that index, in a buffer allocated on the heap.
If the directory part of the URL contains a `%00` sequence, the directory length might end up shorter than the file name path, making the calculation `size_t index = directory_len - file

curl: FTP path trickery leads to NIL byte out of bounds write

CVE-2018-1000120 [CRITICAL] CWE-787 curl: FTP path trickery leads to NIL byte out of bounds write
curl: FTP path trickery leads to NIL byte out of bounds write
A buffer overflow exists in curl 7.12.3 to and including curl 7.58.0 in the FTP URL handling that allows an attacker to cause a denial of service or worse.
It was found that libcurl did not safely parse FTP URLs when using the CURLOPT_FTP_FILEMETHOD method. An attacker, able to provide a specially crafted FTP URL to an application using libcurl, could write a NULL byte at an arbitrary location, resulting in a crash or an unspecified behavior.
Mitigation: Preventing application from using non-default CURLOPT_FTP_FILEMETHOD will avoid triggering the vulnerable code.

CVE-2018-1000120 curl: FTP path trickery leads to NIL byte out of bounds write
It was found that curl can be fooled into writing a zero byte out of bounds.
This bug can trigger when curl is told to work on an FTP URL, with the setting
to only issue a single CWD command (`--ftp-method singlecwd` or the libcurl
alternative `CURLOPT_FTP_FILEMETHOD`).
curl then URL-decodes the given path, calls strlen() on the result and deducts
the length of the file name part to find the end of the directory within the
buffer. It then writes a zero byte on that index, in a buffer allocated on the
heap.
If the directory part of the URL contains a "%00" sequence, the directory
length might end up shorter than the file name path, making the calculation

One Bad Apple Spoils the Barrel: Understanding the Security Risks Introduced by Third-Party Components in IoT Firmware
## Abstract
Currently, the development of IoT firmware heavily depends on third-party components (TPCs) to improve development efficiency. Nevertheless, TPCs are not secure, and the vulnerabilities in TPCs will influence the security of IoT firmware. Existing works pay less attention to the vulnerabilities caused by TPCs, and we still lack a comprehensive understanding of the security impact of TPC vulnerability against firmware. To fill in the knowledge gap, we design and implement , which leverages syntactical features and control-flow graph features to detect the TPCs in firmware, and then recognizes the corresponding vulnerabilities. Based on , we present the first l

## Abstract
Network systems often contain vulnerabilities that remain unfixed in a network for various reasons, such as the lack of a patch or knowledge to fix them. With the presence of such residual vulnerabilities, the network administrator should properly react to the malicious activities or proactively prevent them, by applying suitable countermeasures that minimize the likelihood of an attack by the attacker.
