1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU72398

Risk: Medium

CVSSv4.0: 1.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-23918

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to improperly imposed security restrictions within the process.mainModule.require() method. A remote user can access non authorized modules.

Mitigation

Install update from vendor's website.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote authenticated user via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Memory corruption

EUVDB-ID: #VU15363

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2017-18258

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The vulnerability exists in the xz_head() function of the GNOME libxml2 library, as defined in the xzlib.c source code due to boundary error in the Lempel-Ziv-Markov (LZMA) decompression feature. A remote unauthenticated attacker can trick the victim into opening a specially crafted LZMA file that submits malicious input, trigger memory corruption and cause the application to crash.

Mitigation

Install update from vendor's website.

3) Stack-based buffer overflow

EUVDB-ID: #VU9691

Risk: Low

CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2017-9048

CWE-ID: CWE-121 - Stack-based buffer overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists in the xmlSnprintfElementContent function of XMLSoft libxml2 due to improper bounds checking in the valid.c code. A remote attacker can send a specially crafted request, trigger stack-based buffer overflow condition and cause the service to crash.

Successful exploitation of the vulnerability results in denial of service.

Mitigation

Install update from vendor's website.
