Vulnerabilities in this advisory

• CVE-2021-22946 — CVE-2021-22946 · CWE-319

  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-2022-1292 — CVE-2022-1292 · CWE-78

  The c_rehash script does not properly sanitise shell metacharacters to prevent command injection.

• CVE-2022-2068 — CVE-2022-2068 · CWE-78

  In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection were found by code review. When the CVE-2022-1292 was fixed it was not discovered that there are other places in the script where the file names of certificates being hashed were possibly passed to a command executed through the shell. This script is distributed by some operating systems in a manner where it is automatically executed. On such operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool.

• CVE-2022-22576 — CVE-2022-22576 · CWE-287

  An improper authentication vulnerability exists in curl 7.33.0 to and including 7.82.0 which might allow reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. This affects SASL-enabled protocols: SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only).

• CVE-2022-24903 — CVE-2022-24903 · CWE-120

  Rsyslog is a rocket-fast system for log processing. Modules for TCP syslog reception have a potential heap buffer overflow when octet-counted framing is used. This can result in a segfault or some other malfunction. As of our understanding, this vulnerability can not be used for remote code execution. But there may still be a slight chance for experts to do that. The bug occurs when the octet count is read. While there is a check for the maximum number of octets, digits are written to a heap buffer even when the octet count is over the maximum, This can be used to overrun the memory buffer. However, once the sequence of digits stop, no additional characters can be added to the buffer. In our opinion, this makes remote exploits impossible or at least highly complex. Octet-counted framing is one of two potential framing modes. It is relatively uncommon, but enabled by default on receivers. Modules `imtcp`, `imptcp`, `imgssapi`, and `imhttp` are used for regular syslog message reception. It is best practice not to directly expose them to the public. When this practice is followed, the risk is considerably lower. Module `imdiag` is a diagnostics module primarily intended for testbench runs. We do not expect it to be present on any production installation. Octet-counted framing is not very common. Usually, it needs to be specifically enabled at senders. If users do not need it, they can turn it off for the most important modules. This will mitigate the vulnerability.

• CVE-2022-27781 — CVE-2022-27781 · CWE-400

  libcurl provides the `CURLOPT_CERTINFO` option to allow applications torequest details to be returned about a server's certificate chain.Due to an erroneous function, a malicious server could make libcurl built withNSS get stuck in a never-ending busy-loop when trying to retrieve thatinformation.

• CVE-2022-27782 — CVE-2022-27782 · CWE-295

  libcurl would reuse a previously created connection even when a TLS or SSHrelated option had been changed that should have prohibited reuse.libcurl keeps previously used connections in a connection pool for subsequenttransfers to reuse if one of them matches the setup. However, several TLS andSSH settings were left out from the configuration match checks, making themmatch too easily.

• CVE-2022-29561 — CVE-2022-29561 · CWE-352

  The web interface of the affected devices are vulnerable to Cross-Site Request Forgery attacks. By tricking an authenticated victim user to click a malicious link, an attacker could perform arbitrary actions on the device on behalf of the victim user.

• CVE-2022-29562 — CVE-2022-29562 · CWE-20

  Affected devices do not properly handle malformed HTTP packets. This could allow an unauthenticated remote attacker to send a malformed HTTP packet causing certain functions to fail in a controlled manner.

• CVE-2022-32207 — CVE-2022-32207 · CWE-276

  When curl < 7.84.0 saves cookies, alt-svc and hsts data to local files, it makes the operation atomic by finalizing the operation with a rename from a temporary name to the final target file name.In that rename operation, it might accidentally *widen* the permissions for the target file, leaving the updated file accessible to more users than intended.

• CVE-2023-36386 — CVE-2023-36386 · CWE-79

  A reflected cross-site scripting (XSS) vulnerability exists in the web interface of the affected application that could allow an attacker to execute malicious javascript code by tricking users into accessing a malicious link. The value is reflected in the response without sanitization while throwing an “invalid params element name” error on the get_elements parameters.

• CVE-2023-36389 — CVE-2023-36389 · CWE-79

  A reflected cross-site scripting (XSS) vulnerability exists in the web interface of the affected application that could allow an attacker to execute malicious javascript code by tricking users into accessing a malicious link. The malformed value is reflected directly in the response without sanitization while throwing an “invalid path” error.

• CVE-2023-36390 — CVE-2023-36390 · CWE-79

  A reflected cross-site scripting (XSS) vulnerability exists in the web interface of the affected application that could allow an attacker to execute malicious javascript code by tricking users into accessing a malicious link. The value is reflected in the response without sanitization while throwing an “invalid params element name” error on the action parameters.

• CVE-2023-36748 — CVE-2023-36748 · CWE-326

  The affected devices are configured to offer weak ciphers by default. This could allow an unauthorized attacker in a man-in-the-middle position to read and modify any data passed over to and from the affected device.

• CVE-2023-36750 — CVE-2023-36750 · CWE-77

  The software-upgrade Url parameter in the web interface of affected devices is vulnerable to command injection due to missing server side input sanitation. This could allow an authenticated privileged remote attacker to execute arbitrary code with root privileges.

• CVE-2023-36751 — CVE-2023-36751 · CWE-77

  The install-app URL parameter in the web interface of affected devices is vulnerable to command injection due to missing server side input sanitation. This could allow an authenticated privileged remote attacker to execute arbitrary code with root privileges.

• CVE-2023-36752 — CVE-2023-36752 · CWE-77

  The upgrade-app URL parameter in the web interface of affected devices is vulnerable to command injection due to missing server side input sanitation. This could allow an authenticated privileged remote attacker to execute arbitrary code with root privileges.

• CVE-2023-36754 — CVE-2023-36754 · CWE-77

  The SCEP server configuration URL parameter in the web interface of affected devices is vulnerable to command injection due to missing server side input sanitation. This could allow an authenticated privileged remote attacker to execute arbitrary code with root privileges.

• CVE-2023-36755 — CVE-2023-36755 · CWE-77
