CVSS: 4.3EPSS: 0%CPEs: 72EXPL: 0CVE-2020-8284 – curl: FTP PASV command response can cause curl to connect to arbitrary host
https://notcve.org/view.php?id=CVE-2020-8284
A malicious server can use the FTP PASV response to trick curl 7.73.0 and earlier into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions. Un servidor malicioso puede usar la respuesta FTP PASV para engañar a curl versiones 7.73.0 y anteriores, para que se conecte de nuevo a una dirección IP y puerto determinados, y de esta manera potencialmente hacer que curl extraiga información sobre servicios que de otro modo serían privados y no divulgados, por ejemplo, haciendo escaneo de puerto y extracciones del banner de servicio A malicious server can use the `PASV` response to trick curl into connecting back to a given IP address and port, and this way potentially make curl extract information about services that are otherwise private and not disclosed, for example doing port scanning and service banner extractions. If curl operates on a URL provided by a user, a user can exploit that and pass in a URL to a malicious FTP server instance without needing any server breach to perform the attack. • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2020-8284.html https://hackerone.com/reports/1040166 https://lists.debian.org/debian-lts-announce/2020/12/msg00029.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DAEHE2S2QLO4AO4MEEYL75NB7SAH5PSL https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NZUVSQHN2ESHMJXNQ2Z7T2EELBB5HJXG https://security.gentoo.org/glsa/202012-14 https://securi • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

Curl before 7.49.1 in Apple OS X before macOS Sierra prior to 10.12 allows remote or local attackers to execute arbitrary code, gain sensitive information, cause denial-of-service conditions, bypass security restrictions, and perform unauthorized actions. This may aid in other attacks. Curl versiones anteriores a 7.49.1, en Apple OS X macOS Sierra versiones anteriores a 10.12, permite a atacantes remotos o locales ejecutar código arbitrario, conseguir información confidencial, causar condición de denegación de servicio (DoS), omitir las restricciones de seguridad y llevar a cabo acciones no autorizadas. Esto puede ayudar en otros ataques. • http://www.securityfocus.com/bid/93055 http://www.securitytracker.com/id/1036858 https://lists.apple.com/archives/security-announce/2016/Sep/msg00006.html •

https://notcve.org/view.php?id=CVE-2019-5443
A non-privileged user or program can put code and a config file in a known non-privileged path (under C:/usr/local/) that will make curl <= 7.65.1 automatically run the code (as an openssl "engine") on invocation. If that curl is invoked by a privileged user it can do anything it wants. Un usuario o programa no privilegiado puede colocar un código y un archivo de configuración en una ruta (path) no privilegiada conocida (bajo C:/usr/local/) que hará que curl anterior a versión 7.65.1 incluyéndola, ejecute automáticamente el código en la invocación (como un "engine" openssl). Si ese curl es invocado por un usuario privilegiado, este puede hacer lo que desee. • http://www.openwall.com/lists/oss-security/2019/06/24/1 http://www.securityfocus.com/bid/108881 https://curl.haxx.se/docs/CVE-2019-5443.html https://security.netapp.com/advisory/ntap-20191017-0002 https://www.oracle.com/security-alerts/cpuapr2020.html https://www.oracle.com/security-alerts/cpuoct2020.html https://www.oracle.com/technetwork/security-advisory/cpuoct2019-5072832.html • CWE-94: Improper Control of Generation of Code ('Code Injection') CWE-427: Uncontrolled Search Path Element •

https://notcve.org/view.php?id=CVE-2018-1000120
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. Existe un desbordamiento de búfer en curl, de la versión 7.12.3 a la 7.58.0, en la gestión de URL FTP que permite que un atacante provoque una denegación de servicio (DoS) o algo peor. 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. • http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/103414 http://www.securitytracker.com/id/1040531 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3157 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2019:1543 https://access.redhat.com/errata/RHSA-2020:0544 https://access • CWE-787: Out-of-bounds Write •
CVSS: 9.8EPSS: 0%CPEs: 38EXPL: 0CVE-2018-1000007 – curl: HTTP authentication leak in redirects
https://notcve.org/view.php?id=CVE-2018-1000007
libcurl 7.1 through 7.57.0 might accidentally leak authentication data to third parties. When asked to send custom headers in its HTTP requests, libcurl will send that set of headers first to the host in the initial URL but also, if asked to follow redirects and a 30X HTTP response code is returned, to the host mentioned in URL in the `Location:` response header value. Sending the same set of headers to subsequent hosts is in particular a problem for applications that pass on custom `Authorization:` headers, as this header often contains privacy sensitive information or data that could allow others to impersonate the libcurl-using client's request. libcurl, desde la versión 7.1 hasta la 7.57.0, podría filtrar accidentalmente datos de autenticación a terceros. Cuando se le solicita que envíe cabeceras personalizadas en sus peticiones HTTP, libcurl enviará primero ese conjunto de cabeceras al host en la URL inicial pero también, si se le pide que siga redirecciones y se devuelve un código de respuesta HTTP 30X al host mencionado en la URL en el valor de la cabecera de respuesta "Location:". El envío de la misma serie de cabeceras a hosts subsecuentes es un problema en particular para las aplicaciones que pasan cabeceras "Authorization:" personalizadas, ya que esta cabecera suele contener información sensible de privacidad o datos que podrían permitir que otros suplanten la petición del cliente que emplea libcurl. • http://www.openwall.com/lists/oss-security/2022/04/27/4 http://www.securitytracker.com/id/1040274 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3157 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2019:1543 https://access.redhat.com/errata/RHSA-2020:0544 https://access.redhat.com/errata/RHSA-2020:0594 https://curl.haxx.se/docs/adv_2018-b3bf.html https://lists.debian.org/debian • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
