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 •
CVSS: 7.5EPSS: 0%CPEs: 40EXPL: 1CVE-2020-8286 – curl: Inferior OCSP verification
https://notcve.org/view.php?id=CVE-2020-8286
curl 7.41.0 through 7.73.0 is vulnerable to an improper check for certificate revocation due to insufficient verification of the OCSP response. curl versiones 7.41.0 hasta 7.73.0, es vulnerable a una comprobación inapropiada para la revocación del certificado debido a una verificación insuficiente de la respuesta OCSP Libcurl offers "OCSP stapling" via the CURLOPT_SSL_VERIFYSTATUS option. When set, libcurl verifies the OCSP response that a server responds with as part of the TLS handshake. It then aborts the TLS negotiation if something is wrong with the response. The same feature can be enabled with --cert-status using the curl tool. As part of the OCSP response verification, a client should verify that the response is indeed set out for the correct certificate. • http://seclists.org/fulldisclosure/2021/Apr/50 http://seclists.org/fulldisclosure/2021/Apr/51 http://seclists.org/fulldisclosure/2021/Apr/54 https://cert-portal.siemens.com/productcert/pdf/ssa-200951.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://curl.se/docs/CVE-2020-8286.html https://hackerone.com/reports/1048457 https://lists.debian.org/debian-lts-announce/2020/12/msg00029.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fe • CWE-295: Improper Certificate Validation •
CVSS: 5.9EPSS: 0%CPEs: 75EXPL: 1CVE-2020-1971 – EDIPARTYNAME NULL pointer dereference
https://notcve.org/view.php?id=CVE-2020-1971
The X.509 GeneralName type is a generic type for representing different types of names. One of those name types is known as EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which compares different instances of a GENERAL_NAME to see if they are equal or not. This function behaves incorrectly when both GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer dereference and a crash may occur leading to a possible denial of service attack. • https://github.com/MBHudson/CVE-2020-1971 http://www.openwall.com/lists/oss-security/2021/09/14/2 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=2154ab83e14ede338d2ede9bbe5cdfce5d5a6c9e https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=f960d81215ebf3f65e03d4d5d857fb9b666d6920 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44676 https://lists.apache.org/thread.html/r63c6f2dd363d9b514d0a4bcf624580616a679898cc14c109a49b7 • CWE-476: NULL Pointer Dereference •

By default, Apache CXF creates a /services page containing a listing of the available endpoint names and addresses. This webpage is vulnerable to a reflected Cross-Site Scripting (XSS) attack via the styleSheetPath, which allows a malicious actor to inject javascript into the web page. This vulnerability affects all versions of Apache CXF prior to 3.4.1 and 3.3.8. Please note that this is a separate issue to CVE-2019-17573. Por defecto, Apache CXF crea una página /services que contiene una lista de los nombres y direcciones de los endpoints disponibles. • http://cxf.apache.org/security-advisories.data/CVE-2020-13954.txt.asc?version=1&modificationDate=1605183670659&api=v2 http://www.openwall.com/lists/oss-security/2020/11/12/2 https://lists.apache.org/thread.html/r51fdd73548290b2dfd0b48f7ab69bf9ae064dd100364cd8a15f0b3ec%40%3Cannounce.apache.org%3E https://lists.apache.org/thread.html/r51fdd73548290b2dfd0b48f7ab69bf9ae064dd100364cd8a15f0b3ec%40%3Cdev.cxf.apache.org%3E https://lists.apache.org/thread.html/r51fdd73548290b2dfd0b48f7ab69bf9ae064dd100364cd8a15f0b3ec%40%3Cusers.cxf.apache.org%3E https://lis • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
