CVSS v3.1 |
| In the Linux kernel, the following vulnerability has been resolved:
can: etas_es58x: populate ndo_change_mtu() to prevent buffer overflow
Sending an PF_PACKET allows to bypass the CAN framework logic and to
directly reach the xmit() function of a CAN driver. The only check
which is performed by the PF_PACKET framework is to make sure that
skb->len fits the interface's MTU.
Unfortunately, because the etas_es58x driver does not populate its
net_device_ops->ndo_change_mtu(), it is possible for an attacker to
configure an invalid MTU by doing, for example:
$ ip link set can0 mtu 9999
After doing so, the attacker could open a PF_PACKET socket using the
ETH_P_CANXL protocol:
socket(PF_PACKET, SOCK_RAW, htons(ETH_P_CANXL));
to inject a malicious CAN XL frames. For example:
struct canxl_frame frame = {
.flags = 0xff,
.len = 2048,
};
The CAN drivers' xmit() function are calling can_dev_dropped_skb() to
check that the skb is valid, unfortunately under above conditions, the
malicious packet is able to go through can_dev_dropped_skb() checks:
1. the skb->protocol is set to ETH_P_CANXL which is valid (the
function does not check the actual device capabilities).
2. the length is a valid CAN XL length.
And so, es58x_start_xmit() receives a CAN XL frame which it is not
able to correctly handle and will thus misinterpret it as a CAN(FD)
frame.
This can result in a buffer overflow. For example, using the es581.4
variant, the frame will be dispatched to es581_4_tx_can_msg(), go
through the last check at the beginning of this function:
if (can_is_canfd_skb(skb))
return -EMSGSIZE;
and reach this line:
memcpy(tx_can_msg->data, cf->data, cf->len);
Here, cf->len corresponds to the flags field of the CAN XL frame. In
our previous example, we set canxl_frame->flags to 0xff. Because the
maximum expected length is 8, a buffer overflow of 247 bytes occurs!
Populate net_device_ops->ndo_change_mtu() to ensure that the
interface's MTU can not be set to anything bigger than CAN_MTU or
CANFD_MTU (depending on the device capabilities). By fixing the root
cause, this prevents the buffer overflow. |
| desknet's NEO V4.0R1.0 to V9.0R2.0 contains a hard-coded cryptographic key, which allows an attacker to create malicious AppSuite applications. |
| When Diffie-Hellman (DH) group Elliptic Curve Cryptography (ECC) Brainpool curves are configured in an SSL profile's Cipher Rule or Cipher Group, and that profile is applied to a virtual server, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. |
| Undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. This issue may occur when a Datagram Transport Layer Security (DTLS) 1.2 virtual server is enabled with a Server SSL profile that is configured with a certificate, key, and the SSL Sign Hash set to ANY, and the backend server is enabled with DTLS 1.2 and client authentication. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. |
| When a per-request policy is configured on a BIG-IP APM portal access virtual server, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. |
| The Orion SMS OTP Verification plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 1.1.7. This is due to the plugin not properly validating a user's identity prior to updating their password. This makes it possible for unauthenticated attackers to change arbitrary user's password to a one-time password if the attacker knows the user's phone number |
| Potential vulnerabilities have been identified in the audio package for certain HP PC products using the Sound Research SECOMN64 driver, which might allow escalation of privilege. HP is releasing updated audio packages to mitigate the potential vulnerabilities. |

| SQL injection in Sergestec's Exito v8.0. This vulnerability allows an attacker to retrieve, create, update, and delete databases through the 'cat' parameter in '/public.php'. |
| HCL BigFix Modern Client Management (MCM) 3.3 and earlier is affected by improper access control. Unauthorized users can access a small subset of endpoint actions, potentially allowing access to select internal functions. |

| The Binary MLM Plan plugin for WordPress is vulnerable to limited Privilege Escalation in all versions up to, and including, 3.0. This is due to bmp_user role granting all users with the manage_bmp capability by default upon registration through the plugin's form. This makes it possible for unauthenticated attackers to register and manage the plugin's settings. |
| The Flex QR Code Generator plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in thesave_qr_code_to_db() function in all versions up to, and including, 1.2.5. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. |
| The onOffice for WP-Websites plugin for WordPress is vulnerable to SQL Injection via the 'order' parameter in all versions up to, and including, 5.7 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Editor-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. |
| The Demo Import Kit plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in all versions up to, and including, 1.1.0 via the import functionality. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. |
| The Task Scheduler plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.6.3 via the “Check Website” task. This makes it possible for authenticated attackers, with Administrator-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. |
| The Dhivehi Text plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'dhivehi' shortcode in all versions up to, and including, 0.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. |
| The URLYar URL Shortner plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'urlyar_shortlink' shortcode in all versions up to, and including, 1.1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. |
