CVE-2021-23336 6 Debian, Djangoproject, Fedoraproject and 3 more 12 Debian Linux, Django, Fedora and 9 more 2024-11-21 4.0 MEDIUM 5.9 MEDIUM
The package python/cpython from 0 and before 3.6.13, from 3.7.0 and before 3.7.10, from 3.8.0 and before 3.8.8, from 3.9.0 and before 3.9.2 are vulnerable to Web Cache Poisoning via urllib.parse.parse_qsl and urllib.parse.parse_qs by using a vector called parameter cloaking. When the attacker can separate query parameters using a semicolon (;), they can cause a difference in the interpretation of the request between the proxy (running with default configuration) and the server. This can result in malicious requests being cached as completely safe ones, as the proxy would usually not see the semicolon as a separator, and therefore would not include it in a cache key of an unkeyed parameter.
CVE-2021-23239 4 Debian, Fedoraproject, Netapp and 1 more 6 Debian Linux, Fedora, Cloud Backup and 3 more 2024-11-21 1.9 LOW 2.5 LOW
The sudoedit personality of Sudo before 1.9.5 may allow a local unprivileged user to perform arbitrary directory-existence tests by winning a sudo_edit.c race condition in replacing a user-controlled directory by a symlink to an arbitrary path.
CVE-2021-23225 2 Cacti, Debian 2 Cacti, Debian Linux 2024-11-21 3.5 LOW 5.4 MEDIUM
Cacti 1.1.38 allows authenticated users with User Management permissions to inject arbitrary web script or HTML in the "new_username" field during creation of a new user via "Copy" method at user_admin.php.
CVE-2021-23215 3 Debian, Fedoraproject, Openexr 3 Debian Linux, Fedora, Openexr 2024-11-21 4.3 MEDIUM 5.5 MEDIUM
An integer overflow leading to a heap-buffer overflow was found in the DwaCompressor of OpenEXR in versions before 3.0.1. An attacker could use this flaw to crash an application compiled with OpenEXR.
CVE-2021-23177 4 Debian, Fedoraproject, Libarchive and 1 more 13 Debian Linux, Fedora, Libarchive and 10 more 2024-11-21 N/A 7.8 HIGH
An improper link resolution flaw while extracting an archive can lead to changing the access control list (ACL) of the target of the link. An attacker may provide a malicious archive to a victim user, who would trigger this flaw when trying to extract the archive. A local attacker may use this flaw to change the ACL of a file on the system and gain more privileges.
CVE-2021-23134 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2024-11-21 4.6 MEDIUM 7.8 HIGH
Use After Free vulnerability in nfc sockets in the Linux Kernel before 5.12.4 allows local attackers to elevate their privileges. In typical configurations, the issue can only be triggered by a privileged local user with the CAP_NET_RAW capability.
CVE-2021-23133 5 Broadcom, Debian, Fedoraproject and 2 more 24 Brocade Fabric Operating System, Debian Linux, Fedora and 21 more 2024-11-21 6.9 MEDIUM 6.7 MEDIUM
A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket.
CVE-2021-22960 3 Debian, Llhttp, Oracle 3 Debian Linux, Llhttp, Graalvm 2024-11-21 5.8 MEDIUM 6.5 MEDIUM
The parse function in llhttp < 2.1.4 and < 6.0.6. ignores chunk extensions when parsing the body of chunked requests. This leads to HTTP Request Smuggling (HRS) under certain conditions.
CVE-2021-22959 3 Debian, Llhttp, Oracle 3 Debian Linux, Llhttp, Graalvm 2024-11-21 6.4 MEDIUM 6.5 MEDIUM
The parser in accepts requests with a space (SP) right after the header name before the colon. This can lead to HTTP Request Smuggling (HRS) in llhttp < v2.1.4 and < v6.0.6.
CVE-2021-22947 8 Apple, Debian, Fedoraproject and 5 more 34 Macos, Debian Linux, Fedora and 31 more 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
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-through the TLS traffic from the legitimate server and trick curl into sending data back to the user thinking the attacker's injected data comes from the TLS-protected server.
CVE-2021-22946 8 Apple, Debian, Fedoraproject and 5 more 37 Macos, Debian Linux, Fedora and 34 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
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 sensitive data in clear text over the network.
CVE-2021-22945 8 Apple, Debian, Fedoraproject and 5 more 25 Macos, Debian Linux, Fedora and 22 more 2024-11-21 5.8 MEDIUM 9.1 CRITICAL
When sending data to an MQTT server, libcurl <= 7.73.0 and 7.78.0 could in some circumstances erroneously keep a pointer to an already freed memory area and both use that again in a subsequent call to send data and also free it *again*.
CVE-2021-22940 5 Debian, Netapp, Nodejs and 2 more 7 Debian Linux, Nextgen Api, Node.js and 4 more 2024-11-21 5.0 MEDIUM 7.5 HIGH
Node.js before 16.6.1, 14.17.5, and 12.22.5 is vulnerable to a use after free attack where an attacker might be able to exploit the memory corruption, to change process behavior.
CVE-2021-22939 5 Debian, Netapp, Nodejs and 2 more 8 Debian Linux, Nextgen Api, Node.js and 5 more 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
If the Node.js https API was used incorrectly and "undefined" was in passed for the "rejectUnauthorized" parameter, no error was returned and connections to servers with an expired certificate would have been accepted.
CVE-2021-22930 4 Debian, Netapp, Nodejs and 1 more 4 Debian Linux, Nextgen Api, Node.js and 1 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
Node.js before 16.6.0, 14.17.4, and 12.22.4 is vulnerable to a use after free attack where an attacker might be able to exploit the memory corruption, to change process behavior.
CVE-2021-22924 7 Debian, Fedoraproject, Haxx and 4 more 53 Debian Linux, Fedora, Libcurl and 50 more 2024-11-21 4.3 MEDIUM 3.7 LOW
libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse, if one of them matches the setup.Due to errors in the logic, the config matching function did not take 'issuercert' into account and it compared the involved paths *case insensitively*,which could lead to libcurl reusing wrong connections.File paths are, or can be, case sensitive on many systems but not all, and caneven vary depending on used file systems.The comparison also didn't include the 'issuer cert' which a transfer can setto qualify how to verify the server certificate.
CVE-2021-22898 6 Debian, Fedoraproject, Haxx and 3 more 12 Debian Linux, Fedora, Curl and 9 more 2024-11-21 2.6 LOW 3.1 LOW
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.
CVE-2021-22895 2 Debian, Nextcloud 2 Debian Linux, Desktop 2024-11-21 4.3 MEDIUM 5.9 MEDIUM
Nextcloud Desktop Client before 3.3.1 is vulnerable to improper certificate validation due to lack of SSL certificate verification when using the "Register with a Provider" flow.
CVE-2021-22890 8 Broadcom, Debian, Fedoraproject and 5 more 11 Fabric Operating System, Debian Linux, Fedora and 8 more 2024-11-21 4.3 MEDIUM 3.7 LOW
curl 7.63.0 to and including 7.75.0 includes vulnerability that allows a malicious HTTPS proxy to MITM a connection due to bad handling of TLS 1.3 session tickets. When using a HTTPS proxy and TLS 1.3, libcurl can confuse session tickets arriving from the HTTPS proxy but work as if they arrived from the remote server and then wrongly "short-cut" the host handshake. When confusing the tickets, a HTTPS proxy can trick libcurl to use the wrong session ticket resume for the host and thereby circumvent the server TLS certificate check and make a MITM attack to be possible to perform unnoticed. Note that such a malicious HTTPS proxy needs to provide a certificate that curl will accept for the MITMed server for an attack to work - unless curl has been told to ignore the server certificate check.
CVE-2021-22885 2 Debian, Rubyonrails 3 Debian Linux, Actionpack Page-caching, Rails 2024-11-21 5.0 MEDIUM 7.5 HIGH
A possible information disclosure / unintended method execution vulnerability in Action Pack >= 2.0.0 when using the `redirect_to` or `polymorphic_url`helper with untrusted user input.
