Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Overread Buffers An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

The internal function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to allocate from the heap. The length value is then subsequently used to iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow. (This bug is almost identical to CVE-2017-8816.)(CVE-2018-14618) - 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.(CVE-2018-1000120) - A NULL pointer dereference flaw was found in the way libcurl checks values returned by the openldap ldap_get_attribute_ber() function. A malicious LDAP server could use this flaw to crash a libcurl client application via a specially crafted LDAP reply.(CVE-2018-1000121) - A buffer over-read exists in curl 7.20.0 to and including curl 7.58.0 in the RTSP+RTP handling code that allows an attacker to cause a denial of service or information leakage.(CVE-2018-1000122) - curl version curl 7.20.0 to and including curl 7.59.0 contains a CWE-126: Buffer Over-read vulnerability in denial of service that can result in curl can be tricked into reading data beyond the end of a heap based buffer used to store downloaded RTSP content.. (CVE-2018-1000301) - 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) - It was found that curl and libcurl might send their Authentication header to a third party HTTP server upon receiving an HTTP REDIRECT reply. This could leak authentication token to external entities.

The affected version is 12.2.1.3. This is a difficult to exploit vulnerability that allows an unauthenticated attacker with network access via HTTP to compromise Oracle HTTP Server. A successful attacks requires human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in takeover of Oracle HTTP Server. (CVE-2018-1000300) - A denial of service (DoS) vulnerability exists in curl due to Buffer Over-read. Affected versions are from curl version 7.20.0 to curl 7.59.0. The vulnerable component can be tricked into reading data beyond the end of the heap. An unauthenticated attacked with network access can exploit this issue to cause the application to stop responding. (CVE-2018-1000301) - A buffer over-read vulnerability exists in curl that could lead to information leakage. Affected versions are from 7.20.0 to curl 7.58.0. A vulnerability in the RTSP+RTP handling code could allows an attacker to cause a denial of service or information leakage. An unauthenticated attacked with network access can exploit this vulnerability to cause a denial of service (DoS) or to leak information from the vulnerable application.

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/415d2e 7cb7), 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.i1/4^CVE-2017-1000254i1/4%0 - 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 last seen 2020-03-19 modified 2018-10-26 plugin id 118418 published 2018-10-26 reporter This script is Copyright (C) 2018-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/118418 title EulerOS Virtualization 2.5.0 : curl (EulerOS-SA-2018-1330) NASL family NewStart CGSL Local Security Checks NASL id NEWSTART_CGSL_NS-SA-2019-0039_CURL.NASL description The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has curl packages installed that are affected by multiple vulnerabilities: - curl version curl 7.20.0 to and including curl 7.59.0 contains a CWE-126: Buffer Over-read vulnerability in denial of service that can result in curl can be tricked into reading data beyond the end of a heap based buffer used to store downloaded RTSP content..

An attacker could potentially use this flaw to hijack the authentication of the connection by leveraging a previously created connection with a different client certificate.(CVE-2016-5420) - It was discovered that libcurl could incorrectly reuse NTLM-authenticated connections for subsequent unauthenticated requests to the same host. If an application using libcurl established an NTLM-authenticated connection to a server, and sent subsequent unauthenticated requests to the same server, the unauthenticated requests could be sent over the NTLM-authenticated connection, appearing as if they were sent by the NTLM authenticated user.(CVE-2015-3143) - 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/415d2e7c b7), 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) - It was discovered that libcurl could incorrectly reuse Negotiate authenticated HTTP connections for subsequent requests. If an application using libcurl established a Negotiate authenticated HTTP connection to a server and sent subsequent requests with different credentials, the connection could be re-used with the initial set of credentials instead of using the new ones.(CVE-2015-3148) - Heap-based buffer overflow in the curl_easy_unescape function in lib/escape.c in cURL and libcurl 7.7 through 7.30.0 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted string ending in a last seen 2020-06-01 modified 2020-06-02 plugin id 125003 published 2019-05-14 reporter This script is Copyright (C) 2019-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/125003 title EulerOS Virtualization 3.0.1.0 : curl (EulerOS-SA-2019-1550) NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2020-0594.NASL description An update for curl is now available for Red Hat Enterprise Linux 7.4 Advanced Update Support, Red Hat Enterprise Linux 7.4 Telco Extended Update Support, and Red Hat Enterprise Linux 7.4 Update Services for SAP Solutions.
