Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
EUVDB-ID: #VU55035
Risk: Medium
CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2020-15522
CWE-ID:
CWE-208 - Information Exposure Through Timing Discrepancy
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The
vulnerability exists due to a timing issue within the EC math library. A remote attacker who can observe timing information for the generation of multiple deterministic ECDSA signatures is able to reconstruct the private key used for encryption.

EUVDB-ID: #VU48199
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2020-26939
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to observable differences in behavior to error inputs within the org.bouncycastle.crypto.encodings.OAEPEncoding component in Legion of the Bouncy Castle BC. A remote attacker can obtain sensitive information about a private exponent by sending invalid ciphertext that decrypts to a short payload in the OAEP Decoder. This causes the application to throw an early exception, potentially leaking some information about the private exponent of the RSA private key performing the encryption.

CVE-ID: CVE-2019-17359
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak in the ASN.1 parser. A remote attacker can send a specially crafted ASN.1 data and cause an OutOfMemoryError and perform denial of service attack.

EUVDB-ID: #VU78328
Risk: Medium
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2023-33201
CWE-ID:
CWE-90 - Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to improper input validation in applications that use an LDAP CertStore from Bouncy Castle to validate X.509 certificates. During the certificate validation process, Bouncy Castle inserts the certificate's Subject Name into an LDAP search filter without any escaping, which leads to an LDAP injection vulnerability. A remote non-authenticated attacker can use a specially crafted X.509 certificate to bypass authentication process and gain unauthorized access to the application.

CVE-ID: CVE-2018-1000180
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the IDIH Visualization (Bouncy Castle Java Library) component in Oracle Communications Diameter Signaling Router (DSR). A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
