Description

An issue was discovered in savignano S/Notify before 4.0.2 for Jira. While an administrative user is logged on, the configuration settings of S/Notify can be modified via a CSRF attack. The injection could be initiated by the administrator clicking a malicious link in an email or by visiting a malicious website. If executed while an administrator is logged on to Jira, an attacker could exploit this to modify the configuration of the S/Notify app on that host. This can, in particular, lead to email notifications being no longer encrypted when they should be.

Technical Analysis

CVE-2023-50930 is a high-severity vulnerability affecting the S/Notify plugin for Jira versions prior to 4.0.2. The vulnerability is a Cross-Site Request Forgery (CSRF) issue that allows an attacker to modify the configuration settings of the S/Notify app while an administrative user is logged into Jira. Specifically, if an administrator clicks on a malicious link or visits a malicious website during an active Jira session, the attacker can exploit this vulnerability to change the S/Notify configuration without the administrator's consent or knowledge. One critical consequence of this exploitation is that email notifications, which are expected to be encrypted, could be altered to be sent unencrypted, exposing sensitive information. The vulnerability does not require prior authentication but does require user interaction (the administrator clicking a malicious link). The CVSS v3.1 base score is 8.3, reflecting high impact on confidentiality and integrity, with low attack complexity and no privileges required. The vulnerability falls under CWE-352 (Cross-Site Request Forgery). No known exploits in the wild have been reported yet, and no official patches are linked in the provided information, though the fix is indicated in version 4.0.2 or later.

Potential Impact

For European organizations using Jira with the S/Notify plugin, this vulnerability poses a significant risk to the confidentiality and integrity of email communications. Since Jira is widely used for project management and issue tracking across various industries in Europe, including finance, government, and critical infrastructure, unauthorized modification of notification settings could lead to leakage of sensitive project data or internal communications. The exposure of unencrypted email notifications could facilitate interception by malicious actors, potentially leading to data breaches or espionage. Additionally, the integrity of Jira configurations could be compromised, undermining trust in the system's security controls. The requirement for an administrator to be logged in and interact with a malicious link means that targeted phishing campaigns could be an effective attack vector. This risk is heightened in environments where administrators have broad privileges and where email notifications contain sensitive or regulated information subject to GDPR and other compliance frameworks.

Mitigation Recommendations

European organizations should immediately verify the version of the S/Notify plugin installed in their Jira environments and upgrade to version 4.0.2 or later where the vulnerability is fixed. Until the patch is applied, organizations should implement the following specific mitigations: 1) Educate Jira administrators about the risks of clicking on unsolicited or suspicious links, especially during active sessions. 2) Employ web filtering and email security gateways to block known malicious URLs and phishing attempts targeting administrators. 3) Restrict administrative sessions to dedicated, isolated environments or use multi-factor authentication to reduce the risk of session hijacking. 4) Monitor Jira logs for unusual configuration changes or unexpected email notification behavior. 5) Consider disabling or limiting the use of the S/Notify plugin if it is not critical to operations. 6) Implement Content Security Policy (CSP) headers and anti-CSRF tokens if possible to reduce the risk of CSRF attacks. 7) Review and tighten email encryption policies and verify that email notifications are encrypted as expected after any configuration changes.
