Overview Recently, NSFOCUS CERT detected that Palo Alto Networks issued a security announcement and fixed the command injection vulnerability (CVE-2024-3400) in PAN-OS. Since GlobalProtect gateway or portal configured in PAN-OS does not strictly filter user input, unauthenticated attackers can construct special packets to execute arbitrary code on the firewall with root privileges. The CVSS score […]

Overview Recently, NSFOCUS CERT detected that JumpServer issued a security announcement and fixed two remote code execution vulnerabilities. At present, the PoC of the vulnerability has been made public. Affected users should take protective measures as soon as possible. CVE-2024-29201: Since the Ansible module in JumpServer does not perform complete input verification, attackers with low-privilege […]

Overview NSFOCUS CERT recently detected that a backdoor vulnerability in XZ Utils (CVE-2024-3094) was disclosed from the security community, with a CVSS score of 10. Because the SSH underlying layer relies on liblzma, an attacker could exploit this vulnerability to bypass SSH authentication and gain unauthorized access to affected systems, allowing arbitrary code execution. After […]

NSFOCUS CERT has detected that details and a proof-of-concept (PoC) tool for a Linux kernel privilege escalation vulnerability CVE-2024-1086, have been publicly disclosed recently. Due to a use-after-free vulnerability in the netfilter: nf_tables component of the Linux kernel, the nft_verdict_init() function allows the use of positive values as a drop error in the hook verdict. […]

Overview Recently, NSFOCUS CERT detected that Atlassian issued a security announcement and fixed the directory traversal vulnerability in Confluence Data Center and Server (CVE-2024-21677), with a CVSS score of 8.3. Unauthenticated attackers need to interact with users, and exploiting this vulnerability can have a great impact on the confidentiality, integrity, and availability of the target […]

Overview Recently, NSFOCUS CERT detected that the runc officially issued a security notice and fixed a container escaping vulnerability (CVE-2024-21626). Since the internal file descriptor of runc is leaked during initialization and the final working directory is not verified to be located in the mount namespace of the container, attackers can conduct container escaping in […]

Overview Recently, NSFOCUS CERT detected that Jenkins issued a security announcement and fixed an arbitrary file reading vulnerability in the Jenkins CLI (CVE-2024-23897). Since one function of its CLI command parser is enabled by default in Jenkins, the specific parser function expandAtFiles can replace the character following the file path in the @ parameter with […]

Overview Recently, NSFOCUS CERT detected that GitLab officially released a security announcement and fixed an arbitrary file write vulnerability (CVE-2024-0402) in GitLab Community Edition (CE) and Enterprise Edition (EE). Due to path traversal issues, authenticated attackers can copy files to any location on the GitLab server when creating workspaces. The CVSS score is 9.9, affected […]

Overview On January 16, NSFOCUS CERT detected that Atlassian officially released a security announcement fixing the remote code execution vulnerability (CVE-2023-22522) in Confluence Data Center and Confluence Server. This vulnerability is caused by template injection. Unauthenticated attackers can inject malicious requests into Confluence pages to implement remote code execution on affected targets. The CVSS score […]

Overview Recently, NSFOCUS CERT detected that GitLab officially released a security announcement and fixed multiple security vulnerabilities in GitLab Community Edition (CE) and Enterprise Edition (EE), including two serious vulnerabilities. Affected users should take protective measures as soon as possible. CVE-2023-7028: In GitLab CE/EE, users can reset their passwords through the auxiliary email address. Due […]
