CVSS: 8.8EPSS: 0%CPEs: 15EXPL: 1CVE-2023-27533 – curl: TELNET option IAC injection
https://notcve.org/view.php?id=CVE-2023-27533
A vulnerability in input validation exists in curl <8.0 during communication using the TELNET protocol may allow an attacker to pass on maliciously crafted user name and "telnet options" during server negotiation. The lack of proper input scrubbing allows an attacker to send content or perform option negotiation without the application's intent. This vulnerability could be exploited if an application allows user input, thereby enabling attackers to execute arbitrary code on the system. • https://hackerone.com/reports/1891474 https://lists.debian.org/debian-lts-announce/2023/04/msg00025.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/36NBD5YLJXXEDZLDGNFCERWRYJQ6LAQW https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230420-0011 https://access.redhat.com/security/cve/CVE-2023-27533 https://bugzilla.redhat.com/show_bug.cgi?id=2179062 • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-75: Failure to Sanitize Special Elements into a Different Plane (Special Element Injection) •

https://notcve.org/view.php?id=CVE-2023-27534
A path traversal vulnerability exists in curl <8.0.0 SFTP implementation causes the tilde (~) character to be wrongly replaced when used as a prefix in the first path element, in addition to its intended use as the first element to indicate a path relative to the user's home directory. Attackers can exploit this flaw to bypass filtering or execute arbitrary code by crafting a path like /~2/foo while accessing a server with a specific user. • https://hackerone.com/reports/1892351 https://lists.debian.org/debian-lts-announce/2024/03/msg00016.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/36NBD5YLJXXEDZLDGNFCERWRYJQ6LAQW https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230420-0012 https://access.redhat.com/security/cve/CVE-2023-27534 https://bugzilla.redhat.com/show_bug.cgi?id=2179069 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
CVSS: 6.5EPSS: 0%CPEs: 16EXPL: 1CVE-2023-23916 – curl: HTTP multi-header compression denial of service
https://notcve.org/view.php?id=CVE-2023-23916
An allocation of resources without limits or throttling vulnerability exists in curl <v7.88.0 based on the "chained" HTTP compression algorithms, meaning that a server response can be compressed multiple times and potentially with differentalgorithms. The number of acceptable "links" in this "decompression chain" wascapped, but the cap was implemented on a per-header basis allowing a maliciousserver to insert a virtually unlimited number of compression steps simply byusing many headers. The use of such a decompression chain could result in a "malloc bomb", making curl end up spending enormous amounts of allocated heap memory, or trying to and returning out of memory errors. A flaw was found in the Curl package. A malicious server can insert an unlimited number of compression steps. • https://hackerone.com/reports/1826048 https://lists.debian.org/debian-lts-announce/2023/02/msg00035.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BQKE6TXYDHOTFHLTBZ5X73GTKI7II5KO https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230309-0006 https://www.debian.org/security/2023/dsa-5365 https://access.redhat.com/security/cve/CVE-2023-23916 https://bugzilla.redhat.com/show_bug.cgi?id=2167815 • CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2022-43552
A use after free vulnerability exists in curl <7.87.0. Curl can be asked to *tunnel* virtually all protocols it supports through an HTTP proxy. HTTP proxies can (and often do) deny such tunnel operations. When getting denied to tunnel the specific protocols SMB or TELNET, curl would use a heap-allocated struct after it had been freed, in its transfer shutdown code path. A vulnerability was found in curl. • http://seclists.org/fulldisclosure/2023/Mar/17 https://hackerone.com/reports/1764858 https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230214-0002 https://support.apple.com/kb/HT213670 https://access.redhat.com/security/cve/CVE-2022-43552 https://bugzilla.redhat.com/show_bug.cgi?id=2152652 • CWE-416: Use After Free •
CVSS: 9.8EPSS: 0%CPEs: 16EXPL: 1CVE-2022-32221 – curl: POST following PUT confusion
https://notcve.org/view.php?id=CVE-2022-32221
When doing HTTP(S) transfers, libcurl might erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the `CURLOPT_POSTFIELDS` option has been set, if the same handle previously was used to issue a `PUT` request which used that callback. This flaw may surprise the application and cause it to misbehave and either send off the wrong data or use memory after free or similar in the subsequent `POST` request. The problem exists in the logic for a reused handle when it is changed from a PUT to a POST. Al realizar transferencias HTTP(S), libcurl podría usar erróneamente la devolución de llamada de lectura (`CURLOPT_READFUNCTION`) para solicitar datos para enviar, incluso cuando se haya configurado la opción `CURLOPT_POSTFIELDS`, si anteriormente se usó el mismo identificador para emitir un `PUT `solicitud que utilizó esa devolución de llamada. Esta falla puede sorprender a la aplicación y hacer que se comporte mal y envíe datos incorrectos o use memoria después de liberarla o algo similar en la solicitud "POST" posterior. • http://seclists.org/fulldisclosure/2023/Jan/19 http://seclists.org/fulldisclosure/2023/Jan/20 http://www.openwall.com/lists/oss-security/2023/05/17/4 https://hackerone.com/reports/1704017 https://lists.debian.org/debian-lts-announce/2023/01/msg00028.html https://security.gentoo.org/glsa/202212-01 https://security.netapp.com/advisory/ntap-20230110-0006 https://security.netapp.com/advisory/ntap-20230208-0002 https://support.apple.com/kb/HT213604 https://support.apple.com/k • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-440: Expected Behavior Violation CWE-668: Exposure of Resource to Wrong Sphere •
