Summary

set_file_metadata in xattr.c in GNU Wget before 1.20.1 stores a file's origin URL in the user.xdg.origin.url metadata attribute of the extended attributes of the downloaded file, which allows local users to obtain sensitive information (e.g., credentials contained in the URL) by reading this attribute, as demonstrated by getfattr. This also applies to Referer information in the user.xdg.referrer.url metadata attribute. According to 2016-07-22 in the Wget ChangeLog, user.xdg.origin.url was partially based on the behavior of fwrite_xattr in tool_xattr.c in curl.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Subverting Environment Variable Values
    The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
  • Footprinting
    An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
  • Exploiting Trust in Client (aka Make the Client Invisible)
    An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
  • Browser Fingerprinting
    An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
  • Session Credential Falsification through Prediction
    This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

    descriptionlibcurl is vulnerable to a heap buffer out-of-bounds read. The function handling incoming NTLM type-2 messages (`lib/vauth/ntlm.c:ntlm_decode_type2_target`) does not validate incoming data correctly and is subject to an integer overflow vulnerability. Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.(CVE-2018-16890) The NTLM authentication feature in curl and libcurl before 7.57.0 on 32-bit platforms allows attackers to cause a denial of service (integer overflow and resultant buffer overflow, and application crash) or possibly have unspecified other impact via vectors involving long user and password fields.(CVE-2017-8816) curl and libcurl before 7.57.0 on 32-bit platforms allow attackers to cause a denial of service (out-of-bounds access and application crash) or possibly have unspecified other impact because too little memory is allocated for interfacing to an SSL library.(CVE-2017-8818) libcurl may read outside of a heap allocated buffer when doing FTP. When libcurl connects to an FTP server and successfully logs in (anonymous or not), it asks the server for the current directory with the `PWD` command. The server then responds with a 257 response containing the path, inside double quotes. The returned path name is then kept by libcurl for subsequent uses. Due to a flaw in the string parser for this directory name, a directory name passed like this but without a closing double quote would lead to libcurl not adding a trailing NUL byte to the buffer holding the name. When libcurl would then later access the string, it could read beyond the allocated heap buffer and crash or wrongly access data beyond the buffer, thinking it was part of the path. A malicious server could abuse this fact and effectively prevent libcurl-based clients to work with it - the PWD command is always issued on new FTP connections and the mistake has a high chance of causing a segfault. The simple fact that this has issue remained undiscovered for this long could suggest that malformed PWD responses are rare in benign servers. We are not aware of any exploit of this flaw. This bug was introduced in commit [415d2e7cb7](https://github.com/curl/curl/commit/415d2e7cb7), March 2005. In libcurl version 7.56.0, the parser always zero terminates the string but also rejects it if not terminated properly with a final double quote.(CVE-2017-1000254) Curl versions 7.14.1 through 7.61.1 are vulnerable to a heap-based buffer over-read in the tool_msgs.c:voutf() function that may result in information exposure and denial of service.(CVE-2018-16842) libcurl is vulnerable to a stack-based buffer overflow.

could trick libcurl to accept a bad length + offset combination that
would lead to a buffer read out-of-bounds.(CVE-2018-16890)

The NTLM authentication feature in curl and libcurl before 7.57.0 on
32-bit platforms allows attackers to cause a denial of service
(integer overflow and resultant buffer overflow, and application
crash) or possibly have unspecified other impact via vectors involving
long user and password fields.(CVE-2017-8816)

cause a denial of service (out-of-bounds access and application crash)

libcurl may read outside of a heap allocated buffer when doing FTP.
When libcurl connects to an FTP server and successfully logs in
(anonymous or not), it asks the server for the current directory with
the `PWD` command. The server then responds with a 257 response
containing the path, inside double quotes. The returned path name is
then kept by libcurl for subsequent uses. Due to a flaw in the string

of this flaw. This bug was introduced in commit
[415d2e7cb7](https://github.com/curl/curl/commit/415d2e7cb7), March
2005. In libcurl version 7.56.0, the parser always zero terminates the
string but also rejects it if not terminated properly with a final
double quote.(CVE-2017-1000254)

Curl versions 7.14.1 through 7.61.1 are vulnerable to a heap-based
buffer over-read in the tool_msgs.c:voutf() function that may result
in information exposure and denial of service.(CVE-2018-16842)

libcurl is vulnerable to a stack-based buffer overflow. The function
creating an outgoing NTLM type-3 header
(`lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()`), generates
the request HTTP header contents based on previously received data.
The check that exists to prevent the local buffer from getting
overflowed is implemented wrongly (using unsigned math) and as such it
does not prevent the overflow from happening. This output data can
grow larger than the local buffer if very large 'nt response' data is
extracted from a previous NTLMv2 header provided by the malicious or
broken HTTP server. Such a 'large value' needs to be around 1000 bytes
or more. The actual payload data copied to the target buffer comes
from the NTLMv2 type-2 response header.(CVE-2019-3822)

libcurl is vulnerable to a heap out-of-bounds read in the code
handling the end-of-response for SMTP. If the buffer passed to
`smtp_endofresp()` isn't NUL terminated and contains no character
ending the parsed number, and `len` is set to 5, then the `strtol()`
call reads beyond the allocated buffer. The read contents will not be
returned to the caller.(CVE-2019-3823)

The FTP wildcard function in curl and libcurl before 7.57.0 allows
remote attackers to cause a denial of service (out-of-bounds read and
application crash) or possibly have unspecified other impact via a
string that ends with an '[' character.(CVE-2017-8817)

set_file_metadata in xattr.c in GNU Wget before 1.20.1 stores a file's
origin URL in the user.xdg.origin.url metadata attribute of the
extended attributes of the downloaded file, which allows local users
to obtain sensitive information (e.g., credentials contained in the
URL) by reading this attribute, as demonstrated by getfattr. This also
applies to Referer information in the user.xdg.referrer.url metadata
attribute. According to 2016-07-22 in the Wget ChangeLog,
user.xdg.origin.url was partially based on the behavior of
fwrite_xattr in tool_xattr.c in curl.(CVE-2018-20483)

A buffer overrun flaw was found in the IMAP handler of libcurl. By
tricking an unsuspecting user into connecting to a malicious IMAP
server, an attacker could exploit this flaw to potentially cause
information disclosure or crash the application.(CVE-2017-1000257)

A heap use-after-free flaw was found in curl versions from 7.59.0
through 7.61.1 in the code related to closing an easy handle. When
closing and cleaning up an 'easy' handle in the `Curl_close()`
function, the library code first frees a struct (without nulling the
pointer) and might then subsequently erroneously write to a struct
field within that already freed struct.(CVE-2018-16840)

Curl versions 7.33.0 through 7.61.1 are vulnerable to a buffer overrun
in the SASL authentication code that may lead to denial of
service.(CVE-2018-16839)"
