Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Server-Side Request Forgery (SSRF)

EUVDB-ID: #VU52501

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2020-11987

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Oracle Communications Offline Mediation Controller: 12.0.0.3.0

Q & A

Can this vulnerability be exploited remotely?

Is there known malware, which exploits this vulnerability?

2) Uncontrolled Recursion

EUVDB-ID: #VU48444

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2020-28196

CWE-ID: CWE-674 - Uncontrolled Recursion

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to uncontrolled recursion in MIT Kerberos 5 (aka krb5) implementation when processing ASN.1-encoded Kerberos messages in lib/krb5/asn.1/asn1_encode.c. A remote attacker can pass specially crafted data to the application that uses Kerberos and perform a denial of service (DoS) attack.

Mitigation

Install update from vendor's website.

3) Server-Side Request Forgery (SSRF)

EUVDB-ID: #VU29068

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2019-17566

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to insufficient validation of "xlink:href" attributes. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.

Mitigation

4) Race condition

EUVDB-ID: #VU48942

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2020-27216

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a race condition. On Unix like systems, the system's temporary directory is shared between all users on that system. A collocated user can observe the process of creating a temporary sub directory in the shared temporary directory and race to complete the creation of the temporary subdirectory. If the attacker wins the race then they will have read and write permission to the subdirectory used to unpack web applications, including their WEB-INF/lib jar files and JSP files. If any code is ever executed out of this temporary directory, this can lead to a local privilege escalation vulnerability.

Mitigation

Install update from vendor's website.

5) Integer overflow

EUVDB-ID: #VU29015

Risk: High

CVSSv3.1:

CVE-ID: CVE-2020-10878

CWE-ID: CWE-190 - Integer Overflow or Wraparound

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation. A remote attacker can use a specially crafted regular expression, trigger integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install update from vendor's website.

6) Buffer overflow

EUVDB-ID: #VU49973

Risk: High

CVSSv3.1:

CVE-ID: CVE-2021-3177

CWE-ID: CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary within the PyCArg_repr in _ctypes/callproc.c. A remote attacker can pass specially crafted input to the Python applications that accept floating-point numbers as untrusted input, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install update from vendor's website.
