| A weakness has been identified in Wuxi Wubang Security Software Wubang Five-in-One Safety Production Management Information System up to 3.5. Affected by this vulnerability is the function DiyFileUpload of the file /ws.asmx. This manipulation causes unrestricted upload. Remote exploitation of the attack is possible. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way. |
| Issue summary: Setting an AES-GCM-SIV IV shorter than the expected nonce
length via EVP_CipherInit_ex() may trigger a heap out-of-bounds read.
Supplying a longer IV is silently truncated instead of rejected.
Impact summary: An application passing a caller-supplied IV of the wrong
length may crash or read beyond its buffer. Because trailing IV bytes are
ignored, an attacker who knows one message and tag may forge messages under a
different IV.
CWE: CWE-125: Out-of-bounds Read
Description: AES-GCM-SIV copies the caller-supplied IV or nonce into its
internal state using a copy whose length is taken from the expected nonce size
rather than from the length the caller actually provided. When the caller
passes a shorter IV, the copy reads past the end of the caller's buffer;
AddressSanitizer confirms a heap out-of-bounds read reached through
EVP_CipherInit_ex() into ossl_aes_gcm_siv_init(). When the caller passes a
longer IV, the implementation silently discards the trailing bytes instead of
rejecting the length.
The truncation breaks the binding between the IV and the computed
authentication tag. An attacker who has observed a message and its tag under
one IV can produce a message and tag that verify under a different IV whose
first bytes match, since the surplus bytes never influence the computation.
The message itself is unchanged, so this is a failure of IV commitment rather
than a classic existential forgery.
Only applications that call EVP_CipherInit_ex() (or the equivalent provider
cipher initialization) with an IV length other than the standard 12 bytes for
AES-GCM-SIV are affected. The severity is limited because the out-of-bounds
read is small and attacker-controlled only in length, and the forgery requires
an unusual IV length choice by the application.
FIPS impact: no
The FIPS modules are not affected by this issue, as AES-GCM-SIV is not an
approved algorithm. |
