Improper Validation of Integrity Check Value

Snap One OvrC Pro devices versions 7.2 and prior do not validate firmware updates correctly. The device only calculates the MD5 hash of the firmware and does not check using a private-public key mechanism. The lack of complete PKI system firmware signature could allow attackers to upload arbitrary firmware updates, resulting in code execution.Show less

A vulnerability was found in ICEPAY REST-API-NET 0.9. It has been declared as problematic. Affected by this vulnerability is the function RestClient of the file Classes/RestClient.cs of the component Checksum Validation. The manipulation leads to improper validation of integrity check value. The attack can be launched remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. Upgrading to version 1.0 is able to address this issue. The patch is named 61f6b8758e5c971abff5f901cfa9f231052b775f. It is recommended to upgrade the affected component. The associated identifier of this vulnerability is VDB-222847.Show less

The fix for CVE-2022-3437 included changing memcmp to be constant time and a workaround for a compiler bug by adding "!= 0" comparisons to the result of memcmp. When these patches were backported to the heimdal-7.7.1 and heimdal-7.8.0 branches (and possibly other branches) a logic inversion sneaked in causing the validation of message integrity codes in gssapi/arcfour to be inverted.Show less

The use of the cyclic redundancy check (CRC) algorithm for integrity check during firmware update makes TRENDnet TV-IP651WI Network Camera firmware version v1.07.01 and earlier vulnerable to firmware modification attacks. An attacker can conduct a man-in-the-middle (MITM) attack to modify the new firmware image and bypass the checksum verification.Show less

The use of the cyclic redundancy check (CRC) algorithm for integrity check during firmware update makes Ubiquiti airFiber AF2X Radio firmware version 3.2.2 and earlier vulnerable to firmware modification attacks. An attacker can conduct a man-in-the-middle (MITM) attack to modify the new firmware image and bypass the checksum verification.Show less

A vulnerability has been identified in LOGO! 8 BM (incl. SIPLUS variants) (All versions < V8.3). Affected devices load firmware updates without checking the authenticity. Furthermore the integrity of the unencrypted firmware is only verified by a non-cryptographic method. This could allow an attacker to manipulate a firmware update and flash it to the device.Show less

An exploitable firmware downgrade vulnerability was discovered on the Netgear WPN824EXT WiFi Range Extender. An attacker can conduct a MITM attack to replace the user-uploaded firmware image with an original old firmware image. This affects Firmware 1.1.1_1.1.9 and earlier.Show less

An exploitable firmware modification vulnerability was discovered on the Netgear WPN824EXT WiFi Range Extender. An attacker can conduct a MITM attack to modify the user-uploaded firmware image and bypass the CRC check. A successful attack can either introduce a backdoor to the device or make the device DoS. This affects Firmware Version: 1.1.1_1.1.9.Show less

An issue was discovered in Qualys Cloud Agent 4.8.0-49. It executes programs at various full pathnames without first making ownership and permission checks (e.g., to help ensure that a program was installed by root) and without integrity checks (e.g., a checksum comparison against known legitimate programs). Also, the vendor recommendation is to install this agent software with root privileges. Thus, privilege escalation is possible on systems where any of these pathnames is controlled by a non-root user. An example is /opt/firebird/bin/isql, where the /opt/firebird directory is often owned by the firebird user.Show less

OpenZeppelin Contracts is a library for secure smart contract development. The functions `ECDSA.recover` and `ECDSA.tryRecover` are vulnerable to a kind of signature malleability due to accepting EIP-2098 compact signatures in addition to the traditional 65 byte signature format. This is only an issue for the functions that take a single `bytes` argument, and not the functions that take `r, v, s` or `r, vs` as separate arguments. The potentially affected contracts are those that implement signature reuse or replay protection by marking the signature itself as used rather than the signed message or a nonce included in it. A user may take a signature that has already been submitted, submit it again in a different form, and bypass this protection. The issue has been patched in 4.7.3.Show less

Honeywell Experion PKS Safety Manager 5.02 has Insufficient Verification of Data Authenticity. According to FSCT-2022-0054, there is a Honeywell Experion PKS Safety Manager unauthenticated firmware update issue. The affected components are characterized as: Firmware update functionality. The potential impact is: Firmware manipulation. The Honeywell Experion PKS Safety Manager utilizes the DCOM-232/485 communication FTA serial interface and Enea POLO bootloader for firmware management purposes. An engineering workstation running the Safety Builder software communicates via serial or serial-over-ethernet link with the DCOM-232/485 interface. Firmware images were found to have no authentication (in the form of firmware signing) and only relied on insecure checksums for regular integrity checks. Firmware images are unsigned. An attacker with access to the serial interface (either through physical access, a compromised EWS or an exposed serial-to-ethernet gateway) can utilize hardcoded credentials (see FSCT-2022-0052) for the POLO bootloader to control the boot process and push malicious firmware images to the controller allowing for firmware manipulation, remote code execution and denial of service impacts. A mitigating factor is that in order for a firmware update to be initiated, the Safety Manager has to be rebooted which is typically done by means of physical controls on the Safety Manager itself. As such, an attacker would have to either lay dormant until a legitimate reboot occurs or possibly attempt to force a reboot through a secondary vulnerability.Show less

An unauthenticated remote attacker could exploit this vulnerability to cause interruptions in the network by sending specially crafted OSPF packets. Successful exploitation requires OSPF to be enabled on an affected device.Show less
