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') •

https://notcve.org/view.php?id=CVE-2023-23914
A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause HSTS functionality fail when multiple URLs are requested serially. Using its HSTS support, curl can be instructed to use HTTPS instead of usingan insecure clear-text HTTP step even when HTTP is provided in the URL. ThisHSTS mechanism would however surprisingly be ignored by subsequent transferswhen done on the same command line because the state would not be properlycarried on. A flaw was found in the Curl package, where the HSTS mechanism would be ignored by subsequent transfers when done on the same command line because the state would not be properly carried. This issue may result in limited confidentiality and integrity. • https://hackerone.com/reports/1813864 https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230309-0006 https://access.redhat.com/security/cve/CVE-2023-23914 https://bugzilla.redhat.com/show_bug.cgi?id=2167797 • CWE-319: Cleartext Transmission of Sensitive Information •

https://notcve.org/view.php?id=CVE-2023-23915
A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause HSTS functionality to behave incorrectly when multiple URLs are requested in parallel. Using its HSTS support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when HTTP is provided in the URL. This HSTS mechanism would however surprisingly fail when multiple transfers are done in parallel as the HSTS cache file gets overwritten by the most recentlycompleted transfer. A later HTTP-only transfer to the earlier host name would then *not* get upgraded properly to HSTS. A flaw was found in the Curl package, where the HSTS mechanism could fail when multiple transfers are done in parallel, as the HSTS cache file gets overwritten by the most recently completed transfer. • https://hackerone.com/reports/1826048 https://security.gentoo.org/glsa/202310-12 https://security.netapp.com/advisory/ntap-20230309-0006 https://access.redhat.com/security/cve/CVE-2023-23915 https://bugzilla.redhat.com/show_bug.cgi?id=2167813 • CWE-319: Cleartext Transmission of Sensitive Information •
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 •
