CVSS: 7.5EPSS: 0%CPEs: 49EXPL: 1CVE-2021-22946 – curl: Requirement to use TLS not properly enforced for IMAP, POP3, and FTP protocols
https://notcve.org/view.php?id=CVE-2021-22946
15 Sep 2021 — A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitiv... • http://seclists.org/fulldisclosure/2022/Mar/29 • CWE-319: Cleartext Transmission of Sensitive Information CWE-325: Missing Cryptographic Step •

https://notcve.org/view.php?id=CVE-2021-22947
15 Sep 2021 — When curl >= 7.20.0 and <= 7.78.0 connects to an IMAP or POP3 server to retrieve data using STARTTLS to upgrade to TLS security, the server can respond and send back multiple responses at once that curl caches. curl would then upgrade to TLS but not flush the in-queue of cached responses but instead continue using and trustingthe responses it got *before* the TLS handshake as if they were authenticated.Using this flaw, it allows a Man-In-The-Middle attacker to first inject the fake responses, then pass-thro... • http://seclists.org/fulldisclosure/2022/Mar/29 • CWE-310: Cryptographic Issues CWE-319: Cleartext Transmission of Sensitive Information CWE-345: Insufficient Verification of Data Authenticity •

23 Aug 2021 — The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.5 and 1.19.x before 1.19.3 has a NULL pointer dereference in kdc/do_tgs_req.c via a FAST inner body that lacks a server field.

11 Jun 2021 — curl 7.61.0 through 7.76.1 suffers from exposure of data element to wrong session due to a mistake in the code for CURLOPT_SSL_CIPHER_LIST when libcurl is built to use the Schannel TLS library. The selected cipher set was stored in a single "static" variable in the library, which has the surprising side-effect that if an application sets up multiple concurrent transfers, the last one that sets the ciphers will accidentally control the set used by all transfers. In a worst-case scenario, this weakens transpo... • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf • CWE-668: Exposure of Resource to Wrong Sphere CWE-840: Business Logic Errors •

08 Jun 2021 — Libgcrypt before 1.8.8 and 1.9.x before 1.9.3 mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm, and the window size is not chosen appropriately. This, for example, affects use of ElGamal in OpenPGP.

26 May 2021 — curl 7.7 through 7.76.1 suffers from an information disclosure when the `-t` command line option, known as `CURLOPT_TELNETOPTIONS` in libcurl, is used to send variable=content pairs to TELNET servers. Due to a flaw in the option parser for sending NEW_ENV variables, libcurl could be made to pass on uninitialized data from a stack based buffer to the server, resulting in potentially revealing sensitive internal information to the server using a clear-text network protocol. curl versiones 7.7 hasta 7.76.1 suf... • http://www.openwall.com/lists/oss-security/2021/07/21/4 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-908: Use of Uninitialized Resource CWE-909: Missing Initialization of Resource •

26 May 2021 — curl 7.75.0 through 7.76.1 suffers from a use-after-free vulnerability resulting in already freed memory being used when a TLS 1.3 session ticket arrives over a connection. A malicious server can use this in rare unfortunate circumstances to potentially reach remote code execution in the client. When libcurl at run-time sets up support for TLS 1.3 session tickets on a connection using OpenSSL, it stores pointers to the transfer in-memory object for later retrieval when a session ticket arrives.
