TP-Link WR841N Router multiple vulnerabilities

RISK EVALUATION Multiple TP-Link products TP-Link Archer C20 V5, Archer C20 6.0, Archer AX53 v1.0 and TL-WR841N v13 are affected by multiple vulnerabilities. The most severe of these vulnerabilities could allow an adjacent, unauthenticated attacker to execute administrative commands. 2...

CVE-2026-40514

SmarterTools SmarterMail builds prior to 9610 are affected by a cryptographic weakness in file and email sharing endpoints. DES-CBC is used with keys and IVs derived from System.Random seeded with insufficient entropy, reducing the seed space to about 19,000 values. An unauthenticated attacker ca...

CVE-2026-40514 SmarterTools SmarterMail < Build 9610 Cryptographic Weakness via Weak RNG

SmarterTools SmarterMail builds prior to 9610 contain a cryptographic weakness in the file and email sharing endpoints that use DES-CBC encryption with keys and initialization vectors derived from System.Random seeded with insufficient entropy, reducing the seed space to approximately 19,000...

CVE-2026-40514: Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG)

SmarterTools SmarterMail builds prior to 9610 contain a cryptographic weakness in the file and email sharing endpoints that use DES-CBC encryption with keys and initialization vectors derived from System.Random seeded with insufficient entropy, reducing the seed space to approximately 19,000...

TP-Link TL-WR841N 安全漏洞

The TP-Link TL-WR841N is a router produced by the TP-Link company. The TP-Link TL-WR841N v13 version has a security vulnerability. This vulnerability stems from the use of DES-CBC encryption in the TDDPv2 debugging protocol, where the key is predictable. This could allow unauthorized attackers to...

CVE-2026-5504

A padding oracle exists in wolfSSL's PKCS7 CBC decryption that could allow an attacker to recover plaintext through repeated decryption queries with modified ciphertext. In previous versions of wolfSSL the interior padding bytes are not validated...

Integer Overflow or Wraparound

Overview Affected versions of this package are vulnerable to Integer Overflow or Wraparound due to an integer overflow in the wcCmacUpdate function. An attacker can generate forged CMAC tags by exploiting the wraparound of the totalSz variable after processing 4 GiB of data, which causes the...
