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 •
CVSS: 7.5EPSS: 0%CPEs: 62EXPL: 1CVE-2020-8285 – curl: Malicious FTP server can trigger stack overflow when CURLOPT_CHUNK_BGN_FUNCTION is used
https://notcve.org/view.php?id=CVE-2020-8285
curl 7.21.0 to and including 7.73.0 is vulnerable to uncontrolled recursion due to a stack overflow issue in FTP wildcard match parsing. curl versiones 7.21.0 hasta 7.73.0 e incluyéndola, es vulnerable a una recursividad no controlada debido a un problema de desbordamiento de la pila en el análisis de coincidencias del comodín FTP Libcurl offers a wildcard matching functionality, which allows a callback (set with `CURLOPT_CHUNK_BGN_FUNCTION`) to return information back to libcurl on how to handle a specific entry in a directory when libcurl iterates over a list of all available entries. When this callback returns `CURL_CHUNK_BGN_FUNC_SKIP`, to tell libcurl to not deal with that file, the internal function in libcurl then calls itself recursively to handle the next directory entry. If there's a sufficient amount of file entries and if the callback returns "skip" enough number of times, libcurl runs out of stack space. The exact amount will of course vary with platforms, compilers and other environmental factors. • http://seclists.org/fulldisclosure/2021/Apr/51 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2020-8285.html https://github.com/curl/curl/issues/6255 https://hackerone.com/reports/1045844 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/debian-lts • CWE-121: Stack-based Buffer Overflow CWE-674: Uncontrolled Recursion CWE-787: Out-of-bounds Write •
